The Light Assault Radio, or AN/PRC-521, is a modern, lightweight, tactical assault VHF Radio. It is soldier friendly, easily maintained and highly portable.
The radio supports both voice and data encryption and can communicate with the Combat Net Radio (Primary) in a fixed frequency mode. This is the smallest, hand-held, front-line radio available to the Army.
The AN/PRC-521 can be used in a variety of hand-held or manpack roles, meeting the needs of dismounted platoons and sections, security personnel, sentries, military police, and emergency forces.
