The Browning M2HB .50cal was undoubtedly one of the best HMGs of World War II. It is still used today. It was renowned for its penetration capacity, as its heavy bullets could go right through the armour of half-tracks, armoured cars and even some light tanks.
Its weight made it very stable allowing accurate bursts of fire. A 20kg tripod was required for the 'ground' type, but also came mounted on vehicles in twin or quad versions. The latter weighed more than 1,000kg and was normally mounted on half-tracks.
