The Praying Mantis was an experimental machine gun carrier designed by a private developer for the British Army during the Second World War Praying Mantis Experimental Machine Gun Carrier
The Tank Museum "The Praying Mantis was the brainchild of Mr E.J. Tapp who wanted to create a low profile weapons carrier that could take advantage of hedges and low walls to hide, but then raise itself up to shoot over them while remaining concealed. Trials showed that the design was impracticable: the controls were difficult to use and the motion made the crews ill."
