As the main APC of the Soviet/Russian army the BTR has a crew of 3 that sits at the front, a passenger compartment in the middle with a door on each side of the vehicle and a rear-mounted engine. It is armed with either a 14.5mm MG or a 30mm auto-cannon and is amphibious.
When targeting this vehicle you should: shoot at it frontally or from the rear, as side shots are tricky and it is easy to hit the passenger compartment missing vital components.
