The BTR-3 is designed to be able to perform multiple roles, such as carrying troops, weapons and other supplies to support armed forces on the battlefield. It can be used as a reconnaissance, combat support and patrol vehicle. The hull of the BTR-3 is designed with all-welded steel armour, which provides maximum ballistic protection to troops against small-calibre automatic weapons. The body of the vehicle is lined with Kevlar liner for better protection.
