The Soviets based the BTR-80 on the BTR-70 APC. It has a single 260-hp, V-8 turbocharged, water-cooled, diesel engine, an improvement over the twin gasoline engines installed in the BTR-60 and BTR-70 vehicles. The reconfigured rear portion of the hull accommodates the new, single engine. The Soviets removed the roof chamfers of the modified BTR-70, raised the rear, and squared off the rearward-sloping engine compartment. Standard equipment includes TNPO vision blocks, TNP-B and TKN-3 optical devices for the driver and commander, an OU-3GA2M infra-red search light, six 81 mm smoke grenade launchers 902V "Tucha", a radioset (R-173 or R-163-50U), an intercom, and hydrojets for amphibious propulsion.
The Soviets modified the truncated cone turret used on the BTR-70 for the BTR-80 by redesigning the mantlet. This allows the 14.5 mm (0.57 in) KPVT and coaxial 7.62 mm (0.3 in) PKT machine guns to be elevated to a maximum of 60 degrees. This high angle of fire is useful in engaging targets on steep slopes, in urban fighting, and for engaging low slow flying air targets. The Soviets have also modified the design and positioning of the firing ports; the ports are now round, rather than tear-shaped, and have ball mounts similar to those used on the BMP-1. The forward firing ports now sit in angled recesses, which allows infantry to fire from the front of the vehicle.
The redesigned side doors are split horizontally. The upper portion opens forward; this gives dismounting troops some protection against small arms fire from the front of the vehicle. The lower portion opens down, forming a step. Six smoke grenade projectors are mounted on the rear of the turret.
The BTR-80 can climb a slope with up to 60% gradient and climb a vertical step of 0.5 m.
In 1984, the Soviets began production of a diesel-engined variant of the BTR-70, which they called the BTR-80. The Soviets have retrofitted some BTR-70s with several of the improvements incorporated into the BTR-80, including the high-angle-of-fire turret. The twin doors are designed to allow the infantry to disembark while the vehicle is in motion, and allow the infantry inside to exit from one side if the other is receiving fire. The 30mm Cannon variants are effective against most targets apart from main battle tanks, against which they can still cause significant damage to optics, weapons, and important systems. The main gun is not stabilized, so accurate fire on the move is limited to low speeds, and the turret's rotation mechanism is manually operated. The gunner sits in a roof-mounted chair located above the flat floor behind the driver/commander and two passengers, and before the passenger bench. The gunner's station is basic, but uncharacteristically spacious for a Soviet armored vehicle. The gunner is equipped with both a day time optical sight and an infrared night sight.

The video shows BTR-82A crew members speaking Russian. It is widely suspected[by whom?] that Russian armoured vehicle units have been directly fighting anti-government groups in Syria.
