The BTR-80 (Russian: бронетранспортёр, romanized: bronetransportyor, lit. 'armoured carrier') is an 8×8 wheeled amphibious armoured personnel carrier (APC) designed in the Soviet Union. It was adopted in 1985 and replaced the previous vehicles, the BTR-60 and BTR-70, in the Soviet Army. It was first deployed during the Soviet–Afghan War. The BTR-80 was developed into the larger BTR-90 in the early 1990s..
The BTR-80 is based on the BTR-70 APC, which itself was based on the BTR-60. The BTR-80 is powered by a single 260-hp V-8 turbocharged water-cooled diesel engine, which offers increased performance and reliability over the twin gasoline engines installed in the BTR-60 and BTR-70 vehicles. The original engine was a 260-horsepower V-8 KamAZ-7403 engine, which was superseded by a 240-horsepower YaMZ-238M2 engine. The vehicle features power steering, a central tire-pressure regulating system, self-recovery winch, automatic fire suppression system in the engine compartment, a NBC system, and hydrojets for amphibious operations. The BTR-80 was designed and manufactured at the Arzamas Machinery Construction Factory, formerly Gorky Automobile Plant.

The vehicle mounts a one-man, manually operated BPU-1 turret, modified from earlier versions to allow for a +60° elevation to engage high elevation targets. The turret mounts a 14.5 mm (0.57 in) KPVT and coaxial 7.62 mm (0.3 in) PKT machine guns, sighted by a x4 daytime sighting system. Later BTR-80 variants mount a OU-ZGA2M spotlight for nighttime use. The hull has three firing ports on each side of the troop compartment, angled to permit forward firing. There is an additional firing port to the right of the commander's position, and a port in each roof hatch. The forward ports were designed for the squad's PKM light machine gun, while the remaining troops fired their AKMS or AK-74 weapons from the side ports. Ancillary fighting equipment includes TNPO vision blocks, TNP-B and TKN-3 optical devices for the driver and commander, an OU-3GA2M infrared search light, six 81 mm smoke grenade launchers 902V "Tucha", a radioset (R-173 or R-163-50U), and a crew intercom. The hull featured a new hatch between the second and third axles, which allowed for quicker and safer dismounts than the legacy BTRs. As with earlier variants, the welded steel armor on the BTR-80 was designed to protect occupants from shell fragments and small caliber bullets. The frontal arc was rated against 12.7mm armor piercing (AP) rounds at 100 meters; the upper hull against 7.62mm AP rounds at 100 meters; the lower hull against 7.62mm rounds at 750 meters

An upgraded version, the BTR-80A, was fielded in 1994. This turret was upgraded with a Shipunov 30mm 2A72 gun (the same as mounted on the BMP-3) and coaxial 7.62mm PKTM machine gun, and six 81mm smoke grenade launchers. Thus equipped, the gunner can engage targets out to 2000 meters with armor-piercing tracer rounds, and 4000 meters using high-explosive incendiary rounds. The turret is powered and mounts the 1PZ-9 day sight, and TPN-3 night sight, which can be replaced with the TPN-3-42 long range night sight. The gunner also has a coaxial searchlight for nighttime engagements. The hull is laid out the same as the BTR-80, with commander and driver stations at the front, troop compartment in the middle, and engine at the rear. Modifications to the base BTR-80 and BTR-80A are detailed below.








Nevertheless, the recognized Ukrainian involvement in the armament (ZTM-2 cannon) and the strong visual resemblance to BTR-3 hints us to state that it is (at least a derivative of) a BTR-3.
