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:
“If in that Syrian garden, ages slain,
You sleep, and know not you are dead in vain,
Nor even in dreams behold how dark and bright
Ascends in smoke and fire by day and night
The hate you died to quench and could but fan,
Sleep well and see no morning, son of man.”
—A.E. (Alfred Edward)
“Laughter on American television has taken the place of the chorus in Greek tragedy.... In other countries, the business of laughing is left to the viewers. Here, their laughter is put on the screen, integrated into the show. It is the screen that is laughing and having a good time. You are simply left alone with your consternation.”
—Jean Baudrillard (b. 1929)
