Soviet amphibious infantry fighting vehicle designed in 1960s when Soviet Union war doctrine assumed that in case of World War III they would invade Western Europe, so the capability to cross rivers or be unloaded from landing ships away from harbours was a vital element of the design. Fast (up to 65 kph), capable to transport 8 soldiers protected from small arms fire. Front armour was shaped with wedge profile that improved the amphibious capability also gave decent protection from fire. BMP-1 had plenty of variants through the years (they are still in active use around the world) from scout version to anti-tank (armed with guided missiles).
Based on true events story of Soviet 9th Company 345th Independent Guards Airborne Regiment surrounded on the Hill 3234 by the overwhelming mujahideen forces during Soviet-Afghan War.
