A support unit for assault troops tasked with destroying coastal defences. During the Normandy landings, two types of LCG were used: the Mark 3 and Mark 4, derived from the LCT 3 and 4, whose landing ramp was converted into a simple bow. Measuring approximately 190 feet long (58 m) they were armed with two British 25 pounder guns, two 20 mm guns and two machine guns. They could accommodate up to 23 gunners.
