sector of fire

Example Usage

Each machine gunner was assigned a sector of fire covering the approaches to the perimeter.

Origin

Developed as formal doctrine in WWI trench warfare when interlocking fields of fire became essential to defensive strategy

Fun Fact

Poor sector of fire discipline contributed to the German breakthrough at Kasserine Pass in WWII, leading to major reforms in U.S. Army tactical training.
