The [https://acre2.idi-systems.com/wiki/radios/bf-888s BF-888S] (colloquially called "Baofeng") is a low cost 5W<ref>Watt; wattage.</ref> 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. It is basically equivalent to the 343 in function, just not the preferred version. Note that this radio cannot communicate to 343's, or vice versa.

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.

The [https://acre2.idi-systems.com/wiki/radios/an-prc-148 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.

The [https://acre2.idi-systems.com/wiki/radios/an-prc-152 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.

The [https://acre2.idi-systems.com/wiki/radios/an-prc-117f 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.

The [https://acre2.idi-systems.com/wiki/radios/an-prc-77 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.

The [https://acre2.idi-systems.com/wiki/radios/sem-52-sl 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.

The [https://acre2.idi-systems.com/wiki/radios/sem-70 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”<ref>German. Has multiple translations; in this context it's likely "display".</ref> will light up the display to show the current frequency. The MHz<ref>Megahertz.</ref> and kHz<ref>Kilohertz.</ref> 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.
