It is often used 'hands free' using a head harness or attached to a combat helmet such as the PASGT, Advanced Combat Helmet, or Marine Lightweight Helmet. It can also be used as a weapons night sight, such as on the M110 SASS. In addition, it was part of the equipment fielded in the US Army's Land Warrior program.
