History

The SCR-694 replaced the SCR-284 and was later replaced by the AN/GRC-9. Designed to provide communication between moving or stationary vehicles or as a portable field radio set, the SCR-694 was originally intended for use by mountain troops and airborne forces but soon became the Army-wide standard at battalion level.

The SCR-694 saw use at regimental division headquarters during the Normandy invasion and the Cabanatuan prison raid as well as by scouts and reconnaissance units in the Pacific War.
