Air Guided Missile: The BRM1 air guided missile is very important to army aviation. The BRM1 was modified from an older missile and equipped with semi-automatic laser guidance to make it accurate to within 3 meters. Its nose was changed from a cusp to rounded and equipped with a laser receiver. Armed helicopters with the BRM1 are capable of precise strikes on soft targets with higher efficiency, at lower cost and with less loss. The BRM1’s laser guidance is similar to that of an anti-tank missile. More importantly, the cost of modifying the older missile is relatively very low.
