The US Army OD Green Whistle dated 1977 is an original issue signaling device produced for military use. Constructed from durable plastic, it features the olive drab (OD) green color standard for US Army field equipment of the era. The whistle is clearly marked with a visible 1977 manufacturing date, placing it in the context of late Cold War-era equipment. Compact and lightweight, it was designed for efficient use in various field operations, including communication and signaling roles where audible alerts were required. This equipment would have been carried by service members for emergency signaling, coordination, and safety purposes. The whistle’s simple design facilitates attachment to lanyards or gear, reflecting the practical requirements of military field use. As an authenticated artifact from 1977, this item represents a standard example of personal signaling equipment used by US Army personnel in the late twentieth century.
