Computerised Basic: a fire control system generation in tanks that provides fundamental computer‑assisted ballistic calculations without advanced targeting aids such as laser rangefinders or thermal imaging.

Type of internal combustion engine fuel, refined from crude oil.

High-Explosive Fragmentation: ammunition that explodes on impact, releasing fragments.

High-Explosive Anti-Tank: a type of projectile that uses a shaped charge to penetrate armor.

Optical device that uses laser pulses to measure the distance to a target with high precision.

A tank with reduced armor and weight for increased mobility.

Nuclear, Biological, Chemical protection for tank crews.

Enhanced low-light visibility through specialized optics or sensors.

A rifled gun has spiral grooves cut into its barrel.

A semi‑automatic transmission in a tank automatically shifts gears using hydraulic or mechanical mechanisms while the driver selects gear positions, reducing manual clutch operation.

Handheld or vehicle-mounted devices that release dense smoke to obscure vision, conceal movements, or screen friendly forces from enemy observation.

Thermal sights are infrared imaging devices mounted on a tank's gunner station that detect heat emitted by objects, enabling target identification and aiming in low‑visibility conditions.

A torsion bar is a steel rod that resists twisting and serves as a spring in tank suspensions, with one end fixed to the hull and the other connected to a lever arm moving the road wheel.

Armour made by welding and rolling homogeneous steel plates.
