{{Wikipedia|Flare (pyrotechnic)}}

'''Signal flares''', also known as '''smokers''', are a type of pyrotechnic that produce a brilliant light or intense heat without an explosion.{{Ref/Novel|Id=tfor|TFoR|Chapter=19|Quote=He pulled the pin and tossed the smoker onto the ground. A moment later, thick clouds of green smoke roiled into the sky.}} Flares are used for signaling, 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 gun]]s or handheld percussive tubes.

==Function==
Flares produce their light through the combustion of a pyrotechnic composition. The ingredients are varied, but often based on strontium nitrate, potassium nitrate, or potassium perchlorate and mixed with a fuel such as charcoal, sulfur, sawdust, aluminium, magnesium, or a suitable polymeric resin. Flares may be colored by the inclusion of pyrotechnic colorants.

==Usage==
Signal flares appear to be standard equipment for [[United Nations Space Command|UNSC]] servicemen. They are typically used to alert allies of a friendly position. They utilize thick, green or white smoke.{{Ref/Level|H3|Sierra 117}}{{Ref/Level|H3ODST|Mombasa Streets}} During the [[Battle of Trove]], [[John Forge]] and his men from the {{UNSCShip|Spirit of Fire}} used [[Recon Team Echo]]'s signal flare to find the missing reconnaissance team's [[M312 Heavy Recovery Vehicle|M312 HRV]].{{Ref/Level|HW|Anders' Signal}} During the [[Battle of Sigma Octanus IV]], [[Harland|Corporal Harland]] used green signal flares to mark his squad's location to a [[D77-TC Pelican|Pelican]] carrying [[SPARTAN-II Program|Spartan-II]] [[Blue Team]].{{Ref/Reuse|tfor}} During the [[Fall of Reach]], [[Noble Team]] used blue and red signal flares to attract the attention of incoming dropships.{{Ref/Level|HR|Exodus}}{{Ref/Level|HR|New Alexandria}} The [[Liang-Dortmund Corporation]] manufactures their own [[Liang-Dortmund red emergency flare|emergency flare]].{{Ref/Map|H5G|March on Stormbreak}}{{Ref/Map|H5G|Escape from ARC}} During the [[Battle for Zeta Halo]], some UNSC servicemen carried flare guns in chest holsters.{{Ref/Game|Id=HINF|HINF|In-game model}}
