There is disclosed a fire suppression mechanism for a military tracked vehicle. The mechanism includes a number of relatively small cylindrical pressure vessels, each having a floating piston that separates the respective cylinder into 2 chambers. Vaporizable liquid fire suppressant material (such as C Br F3) occupies one chamber; an inert pressurized gas such as nitrogen occupies the other chamber. An electrically-controlled valve at one end of each cylinder can be remotely triggered open to enable fire suppressant vapor to be discharged from the cylinder under the driving force provided by the pressure of the inert gas; the floating piston shifts along the cylinder as the vapor is discharged from the cylinder toward the developing fireball within the vehicle. Each cylinder is oriented in a horizontal prone position at a central point in the vehicle.
