U.S. Armed Forces equipment

The wireless equipment of the U.S. Armed Forces usually bear designations for the set itself and designations for equipment sets consisting of various individual units, such as complete radio stations.

American equipment was widely used in many Allied countries and throughout Western Europe after the end of World War II, when U.S. equipment was sold cheaply as surplus.
