Smoke Screen

 

an artificially created cloud of smoke or haze which impedes enemy observations and aimed fire (bombing) and conceals the operations of friendly forces. The effectiveness of a smoke screen depends on meteorological conditions and, above all, wind velocity and direction. Smoke screens may be used for either blinding or camouflaging purposes; they may be employed in frontal, flank, or rear positions, as well as in false directions, and, depending on implementation, may be either mobile or stationary. Smoke screens are created by means of smoke pots, grenades, shells, bombs, and smoke generators mounted either in stationary positions or on motor vehicles, tanks, planes, and ships.
