Abstract
Abstract A device comprising an infrared signature cloaking round forming part of the ammunition load of a cannon-armed vehicle provides an immediate response to a hostile threat from IR tracked or IR guided weapons by forming, when fired from the cannon, a mist that absorbs, scatters, reflects, refracts, or diffracts the infrared signature of the vehicle.
