The radio entered Vietnam in 1965 and was carried in virtually all land vehicles, riverboats, and aircraft.

Developed in the late 1950s as a replacement for the Korean War-era AN/PRC-10, the AN/PRC-25, or “Prick 25,” incorporated pioneering solid-state circuitry. Additionally, it was water resistant, simple to operate and easy to maintain. Its 50 Hz “squelch feature,” muting routine background noise when a strong signal wasn’t detected, simplified tuning.

The radio had two antennas, a 3-foot standard antenna for most missions and a 10-foot long-range antenna carried in a canvas bag attached to the radio’s side.

The AN/PRC-25 pack consisted of two metal cans. The lower can contained the battery pack; the upper the transceiver.

The batteries were good for two to three hours of heavy use and could last for several days if used sparingly. The radios also could run off a vehicle’s power supply.

The “Prick 25” remained in service well into the 1980s.​
