The [https://acre2.idi-systems.com/wiki/radios/an-prc-77 AN/PRC-77] (colloquially called "117") is a 4W 1-3km range radio introduced during Vietnam in 1968. It was used primarily as a squad-level radio so you’ll usually see it with radiomen and potentially in vehicles. It’s also often used for operations as far back as World War III as a substitute to other radios of the time. The radio covers a wide range of frequencies. Use the 2 tuning dials on the left and right of the number display to set one. The band switch simply switches you to and from higher and lower band frequencies effectively granting more options for radio traffic. The volume knob goes at 10 different levels and is properly labeled on the right.

=== Vehicle racks ===
=== Vehicle racks ===
One last thing to understand about radios for the Standard Qualifications is what ''vehicle racks'' are. These radios are either "hard" mounted, meaning it's embedded into the vehicle in some way and cannot be removed, or "soft" mounted, meaning the radio can be removed and put back. If it's soft mounted, it's likely to be the 117, 77, or SEM 70. The important point to understand is that a vehicle rack should be preferred when possible because it's range is much better than anything hand held. Racks are sometimes locked to specific seats in a vehicle, and ''sometimes'' can be accessed from outside of it.  
A vehicle rack is a radio mounted to a vehicle. A vehicle rack should be preferred when possible because it's range is much better than anything hand held. Accessing a vehicle rack is sometimes locked to specific seats in a vehicle. They can also sometimes be accessed from outside the vehicle, but you usually need to get in and out at least once for that option to appear.  


However, in cases where the rack can be accessed from outside, the player wishing to do so will need to get in and out of the vehicle at least 1 time to initialize such an option.
=== Multiple radios ===
Sometimes, especially for leadership roles, a person will operate more than 1 radio. This is usually a combination of short and long range radios. One can hear as many radios as they can carry, but ACRE2 only lets you have a key to talk on 3 at a time.


=== Multiple radios ===
The keybinds to talk on the radios correspond to the PTT1-3 settings for ACRE2. Which radio corresponds to what key is determined by the order the radios enter your inventory. There is a number next to the radio in the inventory that indicates this.
Sometimes, especially for leadership roles, a person will operate more than 1 radio. This is usually a 343 and, say, a 152. The keybinds to talk on the radio correspond to the PTT1-3 settings for ACRE2. Which radio corresponds to what key is determined by the order the radios enter one's inventory and are clearly labeled in the inventory by a number to the side of the radio's name.


PTT1 is {{Key press|Caps Lock}}, PTT2 is {{Key press|LCtrl|Caps Lock}}, and PTT3 is {{Key press|LAlt|Caps Lock}}. It is strongly advised {{Key press|LAlt|Caps Lock}} be changed to something else, as {{Key press|LAlt}} is for free look and the keybinds will conflict.

== Advanced communication ==
== Advanced communication ==
In SQ-1, some basic radio communication was discussed. In SQ-2, we are going to get slightly more advanced.
=== Controlled and uncontrolled environments ===
=== Controlled and uncontrolled environments ===
Certain radio frequencies are ''controlled'' or ''uncontrolled''. This is a fancy way of saying that some environments have stricter standards on brevity and use of prowords (or "procedure words"), while others are far more laid back. Generally speaking, short-wave radios designed for communication within a fireteam or squad are ''uncontrolled.'' General chit-chat is expected (to a reasonable degree),  procedural words are entirely unnecessary, and so on. Conversely, radio frequencies with a decent range and which are communicating with a completely different element (e.g full squad to another full squad), and/or a ''command'' element, are ''controlled.'' Unnecessary chatter is strongly discouraged, and procedural words are desired if not required.
Certain radio frequencies are ''controlled'' or ''uncontrolled''. Simply put, a controlled environment has strict standards on "procedure words" and brevity, while uncontrolled environments do not. Short range radios are usually uncontrolled. Long range radios are usually controlled.


=== Over and out ===
=== Over and out ===
For the sake of brief and easily digestible communications, in a controlled radio environment, when someone communicates a message and expects a reply, they end the message with "over". If said person does ''not'' expect a reply, they say "out". The 2 words are ''not'' synonymous, and the distinction between the 2 is a major reason why the phrase "over and out" as used in media is perceived as humorous.
For the sake of brief and easily digestible communications, on a controlled frequency, when someone communicates a message and expects a reply, they are to end the message with "over". If said person does ''not'' expect a reply, they end the message with "out".


Consider the following conversation.
Consider the following conversation.
Line 288: Line 288:
</blockquote>
</blockquote>


This conversation is problematic. At any point one could make a reasonable judgment call that a reply isn't needed, yet, the conversation continues. In fact, after Bravo Two told Alpha One they are approaching the objective, it's entirely reasonable that Alpha One not respond at all, having interpreted it as purely informational. As the element leaders keep giving or receiving replies in this manner, they become distracted. While a certain level of multi-tasking comes with the job, the problem is that the distraction in this situation is ''unexpected'' when it ''doesn't need to be.'' This detracts from the leader's ability to concentrate on leading their element, which could spell disaster.
At any point in this conversation it would be reasonable to assume it had ended. Because neither speaker is certain of when a reply is wanted, the speakers become distracted, not wanting to do something else and get interrupted. While multi-tasking is part of leading, the issue is this distraction is ''avoidable''.


Consider the same conversation when "over" and "out" are used.

''Roger that. Will advise when set.'' '''Out.'''
''Roger that. Will advise when set.'' '''Out.'''


</blockquote>When used properly, it is very clear when a reply is wanted versus when the conversation has come to a close. When Alpha One opens the conversation, Bravo Two knows that they must reply. Then, once Alpha One says "out" at the end, the Bravo Two knows he does not need to say anything, and can now fully focus his attention on whatever objective his element needs to tackle.
</blockquote>It is clear when replies are wanted, and once "out" is invoked, both participants can confidently begin doing other things, knowing they will not be unnecessarily interrupted.


=== You, me, net ===
=== You, me, net ===
When you are are about to speak in a controlled radio environment, or otherwise know you are trying to reach someone over a long distance, you should first identify who you want to reach, then identify who you are, and then monitor the "net" {{Emdash}} or frequency {{Emdash}} for a reply. In some situations the "net" part of this shorthand means to verbally state the radio frequency you are on. Which one is appropriate is situational; doing 1 over the other is not inherently wrong by EDC's standards. The example conversation in the section [[Standard Qualification 2#Over and out|Over and out]] is a good showcase of this shorthand.  
When beginning to speak on a controlled frequency, first identify who you want to reach, then identify who you are, then monitor the "net" {{Emdash}} frequency {{Emdash}} for a reply. Sometimes the "net" portion of this shorthand means to verbally state the current frequency. Whether doing that is necessary is situational. The example conversation in section [[Standard Qualification 2#Over and out|Over and out]] is a good showcase of this shorthand.


This is ''not'' required for ''every transmission in the resultant conversation''. Once you reach the intended recipient, you should still be brief and use "over" and "out" as best you can, but you don't need to keep saying their name and your own.  
Please note that this is ''not'' required for ''every transmission in the resultant conversation''.  


=== Roger and wilco ===
=== Roger and wilco ===
To reply to a message with "roger" is to indicate it has been received. EDC also very commonly uses "copy" or "copy that" for this purpose. Replying with "wilco" is reserved for when the message is an order in which you indicate you both have received it and declare an intention to follow it through. Unless stated otherwise by operation leadership, strict adherence to separating the use of "roger" versus "wilco" is unnecessary. For the purposes of this certification, you are simply expected to know that the 2 responses can have different meanings.
"Roger" indicates a message is received. EDC also commonly uses "copy" and "copy that" to indicate this. "Wilco" is slightly different, indicating a message with an ''order'' is received ''and'' will be carried out.
 
Unless stated otherwise by operation leadership, strict adherence to separating the use of "roger" versus "wilco" is unnecessary. For the purposes of this certification, you are simply expected to know that the 2 responses have different meanings.


=== ACE reports ===
=== ACE reports ===
A leader in your element may call for what is referred to as an "ACE report". This is simply you indicating, using the stoplight color system of "green, yellow, red", followed by "black", how your situation is. Generally the report will have some kind of descriptor (e.g "how's your ammo?", "how are we doing on causalities?", etc) describing what the leader wants specifically. If not, you'd do your best to compress everything into a color. Just do your best.
You may sometimes be asked to make an "ACE report". This is done by using the stoplight color system, plus black, to indicate your condition. ACE report requests are usually specific, like "how's everyone's ammo" or some such. If not specific, do your best to encompass your condition in totality with a single color.


The following table provides examples of certain ACE reports and what a particular response would mean.

[[File:Sq2-combat-stance.JPG|thumb|The left image is a soldier performing a crouch. The right is after {{Key press|Shift|S}}.|336x336px|none]]In Arma, there are combat stances. These are step leans, where your character steps in the specified direction without changing their facing, and then high and low variations of standing, crouching, and being prone.
 
To perform a specific stance, press {{Key press|Shift}} followed by {{Key press|W}}, {{Key press|A}}, {{Key press|S}}, or {{Key press|D}}.


These stances can be achieved via {{Key press|Shift}} followed by {{Key press|W}}, {{Key press|A}}, {{Key press|S}}, or {{Key press|D}}. {{Key press|Shift|W}} will raise you up slightly and {{Key press|Shift|S}} will lower you slightly. {{Key press|Shift|A}} will have you perform a "step lean" to the left (your character will literally take a step towards the left rather than standing at their center of gravity) which, at the same time, will result in your firearm shifting to your left shoulder. This is incredibly useful when needing to hold a left-sided corner. {{Key press|Shift|D}} will have you perform a step lean to the right.
* {{Key press|Shift|W}} will perform the high variation.
* {{Key press|Shift|S}} will perform the low variation.
* {{Key press|Shift|A}} will perform a step lean to the left ''and'' change your weapon to the left shoulder.  
** Useful for covering or clearing a left-sided corner.
* {{Key press|Shift|D}} will perform a step lean to the right.


When you do {{Key press|Shift|A}} or {{Key press|Shift|D}} while prone, your character will adjust so they are laying horizontally with their upper body going towards the left or right, respectively.
A step lean performed while prone will result in your character shifting to lay horizontally with their upper body in the specified direction. Useful to cover a corner while prone.


Something very good to note is that a step lean is ''independent'' of the regular lean that is accomplished with {{Key press|Q}} and {{Key press|E}}, thus allowing you to lean much farther in either direction than you otherwise would ''without'' the step lean.  
Step leans are ''independent'' of the typical leaning achieved with {{Key press|Q}} and {{Key press|E}}, allowing a farther lean that would be possible without it.

Standard Qualification 2 (SQ-2) is a certification that builds upon Standard Qualification 1 to provide further information that full and regular members are expected to know as a baseline. It is part of a series of 2 certifications which are part of advancement in the Arma unit.

DescriptionSlightly more advanced information that the Endurance Coalition requires for more consistent play. Required to progress to a full member.


Arsenals and kit making

This certification will focus on using the ACE arsenal rather than vanilla, given there will rarely — if ever — be a situation where you are given a vanilla arsenal. In such an event, what you learn about ACE arsenals will be enough to get around the vanilla variant.

Arsenal use

While many operations have kits pre-made, sometimes the intent is for you to create your own kit.

A visual depiction of a portion of the arsenal UI.

Kits are built using an in-game tool known as the "arsenal". The arsenal provides an interface to change your clothing, firearms, ammunition, equipment, and attachments. Interacting with the arsenal is done by ACE interacting[1] (LCtrl+⊞ Win) on the container acting as the arsenal. You will then see your avatar from the 3rd person and a UI appear.

On the left you'll see a list of firearm types, the clothing available, and then uncategorized equipment (e.g night-vision, map, compass). On the right you will see the attachments and ammunition for the firearms, and what can be inserted into the various clothing types. So, for example, if you want to add a grenade to your vest, you'd select your vest on the left and then select the amount of grenades you want from the right.

At the very bottom of the UI on the left, you will see a weight indicator.

The ACE arsenal total weight indicator.

This is your total weight. On the very bottom of the right, when adding items to your clothing, you will see a white bar.

The ACE arsenal weight bar.

This is a visual representation of how full the clothing item you are inserting items into (e.g uniform, vest, backpack) is. This bar will increase or decrease when items are added or removed.

When you have selected a firearm on the left, you will notice a small popup near the top left of the UI.

The ACE arsenal weapon information pages.

This lists the specifications of the firearm in question.

Kits

Your kit should never possess a GPS device without the explicit approval of leadership in some manner.

For the absolute basics — the bare minimum necessities you need in 99% of cases — you should be taking the following.

Item Minimum Amount ACE Category
Primary Weapon Magazine 6 (+1 in the gun) Magazines
Secondary Weapon Magazine 2 (+1 in the gun) Magazines
Magazine for Auto-riflemen (Team Dependent) Magazines
Chem-lights (Team Dependent) Grenades
Frag Grenade 1 Grenades
Smoke Grenade (White) 1 Grenades
Canteen 1 Field Rations
Sunflower Seeds/Small Snack 1 Field Ratons
Earplugs 1 (MAX) Misc. Items
Cable Ties 3 Misc. Items
Radio 0 (Mission Dependent) Misc. Items
Mag Lite XL50[2] 1 (MAX) Tools
Entrenching Tool 1 (MAX) Tools
Bandage (Basic) 10 Medical Items
Bandage (Quick Clot 6 Medical Items
Morphine Autoinjector 1 Medical Items
Splint 1 Medical Items
Suture[3] 5 Medical Items
Tourniquet (CAT 1 (Max 4) Medical Items
Map 1 (Left UI)
Compass 1 (Left UI)
Watch 0 (Left UI)

Operation leaders always trump the kits in this section, so if deviating from the above is intentional, that's okay. However, if it is not clearly intentional, and your kit is lacking in the above, it's likely someone is in error.

Many roles — and sometimes it's specified for a whole element by leadership — have something called a march load. This is the maximum weight a kit for that role may have. This is set to balance firepower versus stamina consumption. You should try to meet this load or be slightly beneath it. If you are too underweight the things you are sacrificing for your low weight are likely to cause problems later.

The following is the example of a riflemen kit with a march load of 60 pounds.

Item Minimum Amount
Rifle Magazines 8 (+1 in the gun)
Handgun Magazines 2 (+1 in the gun)
Chem-lights 6
M67 Frag Grenade 3
V40 Mini-Grenades 2
M83 Smoke Grenades (White) 13
Canteen 1
Sunflower Seeds 1
Earplugs 1
Cable Ties 3
AN/PRC-343 Radio 1
Mag lite XL50 1
Entrenching Tool 1
Bandage (Basic) 16
Bandage (Quick Clot) 8
Tourniquet (CAT) 2
Suture 5
Splint 1
Morphine Autoinjector 1

This solder is wearing a light plate-carrier and light backpack. Without the above, they are 37.8 pounds. With, it's 59.7 pounds. Note how most of the changes are from adding bandages, grenades, and magazines. Those items, along with what you are wearing, are usually the biggest contributors to weight.

Note the above kits are examples. Ultimately, what to add in your kit is going to depend on the operation. The above is meant to give you a foundation to learn from.

The recommended weight for the basic riflemen, presuming a march load is not set and you are told to make a kit, is 60 pounds. The advised weight for the other roles, such as AT or medic, will be defined in their specific certifications.

Buddy check

A buddy check is when another person — usually your battle buddy for the operation — sanity checks your kit. A check is physically performed by doing the following.

  1. Holster your weapon entirely by pressing 0.
  2. Use ACE self-interact and select the option where you surrender.
  3. Your buddy will then use normal ACE interaction to open your inventory which was made possible with your surrender.

You will then do the same for your buddy. Or vice versa.

Advanced weapons

Ranging

Screenshot of the range indicator of the UI highlighted.

All firearms have an effective range. The range of your firearm is shown above your stamina bar (see above image). The range indicates that when you aim with a scope or iron-sight, not accounting for factors such as wind, the bullet is expected to reach that range at the middle of your crosshair before being affected by bullet drop.

Certain firearms can have this range changed by adjusting the scope, where when looking through the scope nothing will appear to be different, but your bullet will (try to) reach the newly set range at the crosshair. By default this is done with Page Up or Page Down to adjust vertically and ⇧ Shift+Page Up or ⇧ Shift+Page Down to adjust horizontally. A vertical adjustment is to account for bullet drop; a horizontal adjustment is to account for wind. Adjusting vertically can also be done with Ctrl+Scroll Wheel up or down.

For the purposes of SQ-2 you only need to know that ranging exists, why you would do it (to increase your accuracy at different distances), and how to vertically adjust.

Swapping to your sidearm

It is faster to pull out your sidearm than it is to reload your primary weapon. If you are in a firefight and go empty, yet the enemy is still within a lethal distance to you, pull out your sidearm rather than reload.

Radios

To pass certification, the prospective member must be able to change volume and channel on the Baofeng, 148, 152, and 117f. The prospective member must then be able to change frequencies on the 77, SEM52, and SEM 70. If what is written below is insufficient, click the hyperlink to go to the ACRE2 documentation for the radio.

In SQ-1, the only radio discussed was the AN/PRC-343 (colloquially called "343"). For SQ-2, we will review all remaining radios.

BF-888S (Baofeng)

Official image of the BF-888S.

The BF-888S (colloquially called "Baofeng") is a low cost 5W[4] portable radio with a range of 4-6km. The radio consists of 2 dials, the one on the left for selecting between 16 channels, and the one on the right for volume.

Programmable radios

The following 3 radios all have default channels with frequencies and optional channel names that can be displayed. Furthermore, all 3 radios will work with each other out of the box without needing extra changes in the radio options.

AN/PRC-148 (148)

Official image of the AN/PRC-148.

The AN/PRC-148 (colloquially called "148") is a 5W 5-7km range portable radio. On the top you’ll find a volume control knob, which will also turn the radio off, and a channel knob with 16 channels. The display will show the preset channel's name.

AN/PRC-152 (152)

The AN/PRC-152 (colloquially called "152") is a 5W 5-7km range portable radio performing much the same as the 148. At the top you will find a function switch that can be used to turn the radio off or to set 1 of 6 preset channels. On the left side you’ll find volume buttons to go up and down. On the keypad you’ll find a button on the bottom right that will increase and decrease the channel presets.

AN/PRC-117F (117)

The AN/PRC-117f (colloquially called "117") is a 20W radio with 10-20km of range, often mounted in vehicles. Despite seeming complex there is little you need to know. On the LCD screen is the preset channel selected. On the bottom left of the keypad will be a volume up and down button. On the bottom right of the keypad will be a preset channel up and down button.

Odds / Older technology

The remaining 3 radios are "odd ones out" and will often be used in operations taking place in the past.

AN/PRC-77 (77)

The AN/PRC-77 (colloquially called "77") is a 4W 1-3km range radio introduced during Vietnam in 1968. It was used primarily as a squad-level radio so you’ll usually see it with radiomen and potentially in vehicles. It’s also often used for operations as far back as World War II as a substitute to other radios of the time.

The radio covers a wide range of frequencies. Use the 2 tuning dials on the left and right of the number display to set frequency. The band switch simply switches between higher and lower frequencies effectively granting more options for radio traffic. The volume knob goes at 10 different levels and is properly labeled on the right.

SEM 52 SL (SEM52)

The SEM 52 SL (colloquially called "SEM52") is a low power radio that was issued to the German army in 1995. It’s a 1W radio with a range of 1-2km. There is a channel preset knob on the left for selecting your channel with an accompanying LCD screen showing what the frequency is. A volume knob on the right will turn the radio off when turned low enough.

SEM 70 (SEM70)

The SEM 70 (colloquially called "SEM70") is a man-pack German radio from 1984. It’s a 4W radio with a 1-3km range and is often mounted in vehicles. At the top left the black button labeled “ANZEIGE”[5] will light up the display to show the current frequency. The MHz[6] and kHz[7] knobs flanking the frequency display are used for adjusting the frequency only. Note the frequency can only change when the middle knob to the top right is set to "HW". Don't worry about all the other knobs.

Vehicle racks

A vehicle rack is a radio mounted to a vehicle. A vehicle rack should be preferred when possible because it's range is much better than anything hand held. Accessing a vehicle rack is sometimes locked to specific seats in a vehicle. They can also sometimes be accessed from outside the vehicle, but you usually need to get in and out at least once for that option to appear.

Multiple radios

Sometimes, especially for leadership roles, a person will operate more than 1 radio. This is usually a combination of short and long range radios. One can hear as many radios as they can carry, but ACRE2 only lets you have a key to talk on 3 at a time.

The keybinds to talk on the radios correspond to the PTT1-3 settings for ACRE2. Which radio corresponds to what key is determined by the order the radios enter your inventory. There is a number next to the radio in the inventory that indicates this.

By default PTT1 is ⇪ Caps Lock, PTT2 is LCtrl+⇪ Caps Lock, and PTT3 is LAlt+⇪ Caps Lock. It is strongly advised LAlt+⇪ Caps Lock be changed to something else, as LAlt is for free look and they binds will conflict.

Advanced communication

Controlled and uncontrolled environments

Certain radio frequencies are controlled or uncontrolled. Simply put, a controlled environment has strict standards on "procedure words" and brevity, while uncontrolled environments do not. Short range radios are usually uncontrolled. Long range radios are usually controlled.

Over and out

For the sake of brief and easily digestible communications, on a controlled frequency, when someone communicates a message and expects a reply, they are to end the message with "over". If said person does not expect a reply, they end the message with "out".

Consider the following conversation.

Bravo Two, this is Alpha One. We are approaching the objective.
Understood, Alpha One. We're setting up overwatch now.
Let us know when you're in position.
Roger that. Will advise when set.

At any point in this conversation it would be reasonable to assume it had ended. Because neither speaker is certain of when a reply is wanted, the speakers become distracted, not wanting to do something else and get interrupted. While multi-tasking is part of leading, the issue is this distraction is avoidable.

Consider the same conversation when "over" and "out" are used.

Bravo Two, this is Alpha One. We are approaching the objective. Over.
Understood, Alpha One. We're setting up overwatch now. Over.
Let us know when you're in position. Over.
Roger that. Will advise when set. Out.

It is clear when replies are wanted, and once "out" is invoked, both participants can confidently begin doing other things, knowing they will not be unnecessarily interrupted.

You, me, net

When beginning to speak on a controlled frequency, first identify who you want to reach, then identify who you are, then monitor the "net" — frequency — for a reply. Sometimes the "net" portion of this shorthand means to verbally state the current frequency. Whether doing that is necessary is situational. The example conversation in section Over and out is a good showcase of this shorthand.

Please note that this is not required for every transmission in the resultant conversation.

Roger and wilco

"Roger" indicates a message is received. EDC also commonly uses "copy" and "copy that" to indicate this. "Wilco" is slightly different, indicating a message with an order is received and will be carried out.

Unless stated otherwise by operation leadership, strict adherence to separating the use of "roger" versus "wilco" is unnecessary. For the purposes of this certification, you are simply expected to know that the 2 responses have different meanings.

ACE reports

You may sometimes be asked to make an "ACE report". This is done by using the stoplight color system, plus black, to indicate your condition. ACE report requests are usually specific, like "how's everyone's ammo" or some such. If not specific, do your best to encompass your condition in totality with a single color.

The following table provides examples of certain ACE reports and what a particular response would mean.

Category "Green" "Yellow" "Red" "Black"
Ammunition 100% of starting amount 50% of starting amount 1 firefight left Completely out, combat ineffective
Medical Supplies 100% of starting amount 50% of starting amount 1 firefight left Completely out, cannot treat any future injury
Casualties No injuries or dead, still combat capable Injuries or losses sustained No longer combat capable Everyone is dead

Advanced movement

Visualizing combat stances in 3rd person at least once is highly advisable.
The stance indicator reflecting that the player is using the crouch's "high" combat stance.
The left image is a soldier performing a crouch. The right is after ⇧ Shift+S.

In Arma, there are combat stances. These are step leans, where your character steps in the specified direction without changing their facing, and then high and low variations of standing, crouching, and being prone.

To perform a specific stance, press ⇧ Shift followed by W, A, S, or D.

  • ⇧ Shift+W will perform the high variation.
  • ⇧ Shift+S will perform the low variation.
  • ⇧ Shift+A will perform a step lean to the left and change your weapon to the left shoulder.
    • Useful for covering or clearing a left-sided corner.
  • ⇧ Shift+D will perform a step lean to the right.

A step lean performed while prone will result in your character shifting to lay horizontally with their upper body in the specified direction. Useful to cover a corner while prone.

Step leans are independent of the typical leaning achieved with Q and E, allowing a farther lean that would be possible without it.

Cover and concealment

A visual aid showcasing the difference between cover and concealment.

When discussing a live fire environment, it is important to understand the concept of cover versus concealment. Something that is cover will hide you from view and stop a bullet. Something that is concealment will hide you from view but will not stop a bullet. Commonly used examples of the difference would be that a large rock is cover while bushes are concealment. However, keep in mind that things can be solid, fully opaque,[8] and still be just concealment.

A common idea shown in media is that a car door will stop bullets. Aside from vehicles designed to be armored, of which even most police vehicles are not, a car door will not stop a bullet, and so in that scenario the door is concealment. The same goes even for (non-brick) walls — the walls of most modern residential buildings will likely not stop a bullet, and thus are concealment.

In video games, walls, car doors, and the like being represented as true cover is typically because it's expected video game behavior and easier to develop. However, understand Arma does not follow this trend. Bullets can and will go through non-armored cars, (some) walls, and other kinds of material.

Cover should always be preferred to concealment when possible. Concealment is more-so used when staying on the move, or bounding, and access to cover is spotty. In a firefight, proper cover should be prioritized immediately.
