LenPRC – 122/N
Manpack Radio Communication System
PRC-122/N as a Manpack radio communication system is designed and manufactured for establishing communication between military units. It is an appropriate substitute for the PRC-77 radio communication system, because its dimension and weight are reduced, its capabilities are improved, and also it can communicate with the other military radio communication systems of the armed forces.
