Purpose and Publication History
Army change publications revised selected material while allowing units to keep an existing manual in service. Issued more than two years after the base edition, this supplement documents the continued updating of that reference during the Cold War. Its November 1975 date places it after the end of the Vietnam War. The Change 4 designation identifies its position in the revision sequence; it does not establish that earlier updates are included.
History of Military Pyrotechnics
Military pyrotechnics developed into several families of devices for signaling, illumination, and training. By the 1950s, U.S. technical manuals documented ground, aircraft, and marine signals alongside specialized items such as photoflash cartridges and training simulators. These devices served different purposes: some produced visible signals, others supplied light, and simulators reproduced battlefield effects during exercises. This range of equipment forms the historical background to the later Military Pyrotechnics manual and its numbered updates.
History of Use
Flares and colored signals helped military personnel communicate, identify locations, and work after dark. During the Vietnam War, AC-47 Spooky gunships used illumination flares while supporting troops and defending bases, airfields, and villages. The aircraft began combat missions in December 1964. Their flare missions provide a documented example of how pyrotechnic equipment supported operations alongside aircraft, radios, and other military systems.
