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:
“As far as I can see, this autumn haze
That spreading in the evening air both ways
Makes the new moon look anything but new
And pours the elm-tree meadow full of blue,
Is all the smoke from one poor house alone....”
—Robert Frost (1874–1963)
“She was custom built for the pictures—teeny tiny, one inch less than five foot, and a perfectly enormous head. Her face went right from one side of the screen to the other. Gloria Swanson was like that, as well. Joan Crawford, too. You need the big face, for the closeups.”
—Angela Carter (1940–1992)
