The United States military uses a variety of different headlamps, depending on the branch of the service and the specific needs of the mission. The most common headlamp used by the Army is the SureFire M951XM07 WeaponLight, which is attached to the M4 carbine rifle. This light is extremely bright and can be used to temporarily blind and disorient an enemy. The Marine Corps also uses this same headlamp on their rifles.
Other branches of the military, such as the Air Force, use different types of headlamps depending on the situation. For example, airmen may use a night vision goggle-compatible headlamp for flying missions in low-light conditions. In general, though, most military headlamps are designed for durability and brightness rather than style or comfort.
