Airborne radars are found on aircraft at both low and high ranks, if an aircraft is equipped with radar then a radar display will be present in the right portion of a player's screen, as well as a compass displaying the player's current heading and the directions to detected targets at the top of the screen.

Update "Wind of Change" added active protection systems (APS) to ground vehicles. These devices provide automatic defense against ATGMs or slow flying shells like HEAT-FS. While it is possible to shoot down incoming ATGMs manually, particularly using machine guns, this can be difficult against fast-moving or minimally visible missiles; thus, active protection systems provide an extra layer of security against ATGM threats.

Anti-tank Guided Missile (ATGM), or simply anti-tank missile, refers to a missile system specialized in destroying heavily armoured vehicles such as tanks.

Optics are a device used by vehicle crews to increase the magnification of the enemy being targeted for a more reliable targeting solution. Typically used in specific modes, optics come into play whenever using the sniper scope (gunner position), the commander's binoculars (from commander's cupola) or scope (from wherever the commander might reside).

The gun stabilizer is a system that improves the tank gun’s aim at the target and preserves (stabilizes) its aim even when the hull vibrates during movement, which allows it to perform effective aimed fire during vehicle movement or when temporarily stopped. This reaction time and accuracy between target detection and effective hit draw the line between life and death in tank warfare. Read more about the gun stabilizers in the article.
