A '''smoke screen''' is [[smoke]] released to mask the movement or location of military units such as [[infantry]], [[tank]]s, [[aircraft]], or [[ship]]s.

Smoke screens are commonly deployed either by a [[wikt:canister|canister]] (such as a [[Smoke grenade|grenade]]) or generated by a vehicle (such as a [[tank]] or a [[warship]]).

Whereas smoke screens were originally 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 they are also available for vehicles in a super-dense form used to block laser beams of enemy [[laser designator]]s or [[rangefinder]]s.
