Cooking off

|
Cooking off is when ammunition is set off prematurely due to heat in the surrounding environment.
Cooking off limits the rate of fire of many rifles, since heavy use will heat up the gun's barrel.
Cooking off is a serious hazard to crews in damaged and disabled tanks. Over the years, many solutions have been tried, including storing the ammunition under water and insulating ammunition compartments. The current technique, used in tanks like the M1 Abrams, is to armor the compartments and provide blow-off panels to channel the force of the explosion to the exterior of the tank.
