PIAT

The Projector, Infantry, Anti Tank (PIAT) was a British hand-held anti-tank weapon developed during the Second World War. The PIAT was designed in 1942 in response to the British Army's need for a more effective infantry anti-tank weapon, and entered service in 1943.

PIAT in Worldwar
The PIAT was first used against the Race during their Invasion of England in 1943. Although not highly thought off by Race Landcriuser crews when compared with the German counterpart, it still didn't make the campaign in England any easier.
