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

Shtora-1 is an electro-optical jammer that disrupts semiautomatic command to line of sight (SACLOS) antitank guided missiles, laser rangefinders and target designators. Shtora-1 is a soft-kill, or passive-countermeasure system. The system was shown fitted to a Russian main battle tank during the International Defense Exposition, held in Abu Dhabi in 1995. The first known application of the system is the Russian T-90 main battle tank, which entered service in the Russian Army in 1993. It is also available on the BMP-3M infantry fighting vehicle.

The Shtora-1 has four key components:

Two electro-optical/infrared (IR) "dazzlers" interface station one each mounted to the left and right of the main gun, which includes an infrared jammer, modulator, and control panel.
