General Description
The M1A2 Infinity Aiming Collimator is an optical instrument used for establishing an optical reference from which weapon deflection angles can be measured for indirect fire. It has an illuminated mil scale reticle which functions as an optical projection system that simulates a grid board type of infinity aiming target reference.
The M1A2, which is illuminated by a battery powered LED, replaced the M1A1 Infinity Aiming Collimator, which is illuminated by radioluminous tritium (3H) lamps.
The M1A2 Infinity Aiming Collimator is used with the M777 (155mm), M198 (155mm), M119 (105mm), M109 (155mm), and many howitzers no longer used by the United States but still in use by foreign militaries.
