Seventy years ago this month, the January 1952 issue of Radio-Electronics showed “the boldest stroke in education by television ever made.” The 31-foot TV truck of the Army Signal Corps would be used to televise intricate military exercises and maneuvers, allowing them to be viewed back at base on television screens by much larger numbers than would otherwise be able to witness them. In fact, the camera would make visible all of the little things you wouldn’t see if you were there, making the experience superior to attending in person.

The signals were relayed back to base with a 7 GHz microwave link.
