Battlefield VietnamThe M40 is issued to USMC and MACV Scout kits on certain maps. It has very high multipliers, a low rate of fire, high recoil, good accuracy and a 6X scope meant for long range engagements. Its high damage can kill an enemy in 2 body shots or a single head shot and its accuracy will make it so it can easily hit a target from 200–250 meters away. Although being difficult to use in close-quarters due to its low rate of fire, the small cross hairs and high damage can prove to be effective when no-scoping. The M40 can somewhat be considered an equivalent to the Viet Cong M91/30.
