Shtora-1 (Russian: Штора, "curtain") is an electro-optical active protection system or suite for tanks, designed to disrupt the laser designator and laser rangefinders of incoming anti-tank guided missiles (ATGMs). The system is mounted on the Russian T-80 and T-90 series tanks and the Ukrainian T-84. The existence of Shtora was revealed in 1980 by spy Adolf Tolkachev.
