The use of SET Screening Smoke devices released to mask the movement or location of military units such as infantry, tanks, aircraft or ships.
SET developed different types of Screening Smokes like:
Hand thrown Grenade e.g. for soldiers to camouflage the position before movement Smoke Grenades for tank or vehicle launchers.
Screening Smoke Blocks to screen large areas e.g. harbors, airfields, ship convoys or facilities.
The devices releases a very dense cloud of smoke designed to fill the surrounding area even in light wind.
