H4855 Personal Role Radio (PRR)
Personal Role Radios (PRR) consist of headsets attached to short range transmitters/receivers worn by British infantry units, at section-level (8 man teams) or below. PRRs allow infantry sections to stay in communication whilst out of line of sight. This is particularly useful when operating in urban environments as the signal is strong enough to propagate through walls. PRRs have proved their worth in both Iraq and Afghanistan although the PRR does suffer from not being securely encrypted.
