Flare (Earth-7149)

A flare, also sometimes called a fusee, is a type of pyrotechnic that produces a brilliant light or intense heat without an explosion. Flares are used for signalling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes.

Flares were used on URNA Outpost 31 in 2560, on Fiorina 161 in 2557, and aboard Sevastopol Station in 2560. The UNSC Marine Corps also employ the use of M-94 marking flares.
