Despite the Browning being the primary machine gun used by the US Army, there seems to have been a unique use of the Vickers in the Second World War by American forces. The US Army Rangers used the Vickers GO No. 1 Mk. I as additional firepower for cliff assaults.
For the Pointe du Hoc assault on 06 June 1944 - Operation Overlord 'D-Day' - they utilised multiple guns at the top of extendable ladders mounted on of DUKW amphibious vehicles. Initially, this was a triple installation in training, but then appears to have been reduced to a pair for the actual operation. This may have been as part of an armoured housing with additional magazines.
The available photos show Twin Vickers K guns mounted on the top of the ladder and a grave at the top of Pointe du Hoc utilising a Vickers GO and US M1 helmet - alongside the gun and helmet is the magazine from the 'K'. This is supplemented by a short Imperial War Museum clip of the Ranger training, showing the triple 'K' mounting.
