The BTR-4 "Bucephalus" is an amphibious 8x8 wheeled armoured personnel carrier (APC) designed in Ukraine by the Kharkiv Morozov Machine Building Design Bureau (SOE KMDB).
They have seen action in both the War in Donbass, and the capture of Jurf Al Nasr from ISIL. On 4 June 2014, company officials revealed that the BTR-4E was being used in military operations in the Sloviansk area. Its armor had withstood hits from large-caliber machine guns, counter-HEAT side screens protected the crew from anti-tank grenade launchers, and armored glass sustained direct hits from sniper rifles. Their original desert camo as seen on Iraqi BTR-4s can be viewed in pictures and videos from ATO operations. Two Ukrainian BTR-4 were captured by the pro-Russian separatists in repairable state.
