The BTR-70 is an eight-wheeled armored personnel carrier originally developed during the late 1970s and fielded by the Warsaw Pact and allies beginning in the early 1980s. Introduced as a successor to the earlier BTR-60, it most closely resembles a BTR-60PB. Other improvements include heavier armor plating and tires less prone to puncture. In other respects, the vehicle is very similar to the BTR-60PB, with a more powerful (although still fuel hungry) engine configuration and armament of a primary heavy machine gun and secondary PKT machine gun on a roof mounted turret.
The vehicle's designers moved the side troop doors. On the vehicle's predecessor, these doors were located above the beltline between the second and third pairs of wheels on both sides of the vehicle. On the BTR-70, the doors are below the beltline between the second and third pairs of wheels. As Soviet doctrine calls for unloading troops from the vehicle while it is in motion, the door location increases the chances that a soldier will be pulled under a wheel and killed.
Like the vehicle's predecessor it is fully amphibious with minimal preparation. A licensed Romanian copy was designated the TAB-77 and had various improvements and changes to make local production easier, including a better turret and different engines.
- Many derelict examples can be found throughout The Zone often with minor caches of loot in what appear to be open access points. Views into the vehicle's interior are also possible through these openings.
- Players should note that too close inspection of these openings will result in the player's actor becoming wedged and trapped there with a reload of a previous save being the only current recourse.
