Protective Smoke Barrier
M1 Abrams can obstruct vision and thermal imaging from the enemy by creating a thick smoke barrier using two six-barreled M250 smoke grenade launchers fitted on the tank’s turret. When the grenades airburst, they produce smoke to shield the vehicle. Along with the grenade launcher, the tanks are equipped with a smoke generator that the driver can trigger. It creates smoke by spraying fuel into hot turbine exhaust. Currently, the smoke generator is disabled on most Abrams due to a shift in fuel from diesel to Jp-8.
