A smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft or ships.
Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or a warship).
Whereas smoke screens would originally have been used to hide movement from enemies' line of sight, modern technology means that they are now also available in new forms; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and also available for vehicles is a superdense form used to prevent laser beams of enemy target designators or range finders on vehicles.

Famous quotes containing the words smoke and/or screen:
“Smoking ... is downright dangerous. Most people who smoke will eventually contract a fatal disease and die. But they don’t brag about it, do they? Most people who ski, play professional football or drive race cars, will not die—at least not in the act—and yet they are the ones with the glamorous images, the expensive equipment and the mythic proportions. Why this should be I cannot say, unless it is simply that the average American does not know a daredevil when he sees one.”
—Fran Lebowitz (b. 1950)
“Between two evils, I always pick the one I never tried before.”
—Raoul Walsh, U.S. screen writer. Frisco Doll (Mae West)
