The SCR-694 was a portable two way radio set used by the U.S. military during World War II.

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 all over the army in many different theaters; notable instances include at regimental division headquarters during the Normandy invasion [1] and the Cabanatuan prison raid[2] as well as by scouts and reconnaissance units in the Pacific War.[3]
