The BTR-80 appeared in the 1980's when it became obvious that the BTR-70 was an inadequate APC (from the Afghanistan experience). Again, it retains the shape of the BTR-60PB and BTR-70 and retains their basic features, including armament, night-vision equipment, NBC protection system etc, amphibious capability etc. The BTR-80 can hold seven men in addition to the two crewmen. There are three forward-facing firing ports along the length of the hull, one at the front of the vehicle for the commander, and two in the roof hatches. The front two firing ports are designed for PK general-purpose machine guns. The remaining firing ports are designed for the AKM/ AK-74 assault rifles.
