Smoke Screen

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:

    O women, kneeling by your altar-rails long hence,
    When songs I wove for my beloved hide the prayer,
    And smoke from this dead heart drifts through the violet air
    And covers away the smoke of myrrh and frankincense;
    Bend down and pray for all that sin I wove in song....
    William Butler Yeats (1865–1939)
