These relatively small ships were used extensively by the British Army during landing maneuvers. The LCA’s key benefits were its low production cost, its speed and its ease of use. After all, with only 4 sailors on board, the ship could carry more than 30 infantrymen. Constructed primarily of wooden planks and some armor, the ship was very light and offered some protection to soldiers, as long as enemy fire directed at them was not too intense. With more than 60 LCAs deployed, the Dieppe Raid was the first large-scale operation involving these ships. A variant of the LCA, the LCP(L) was used by the Fusiliers Mont-Royal during the Dieppe Raid. However, because they were built only with plywood, they did not stand up well to German fire and were not suitable for a raid of the scale of Dieppe.

Numerous tanks were mobilized for the Raid. The first LCT ships were designed in 1940 by the British government and up until the Dieppe raid, quite a few of these models were built. During the raid, it was the LCT Mark 4, built especially to cross the English Channel, that was used. An imposing ship, it could carry up to six Churchill tanks at the same time. A few LCM Mark 1s were also mobilized in preparation for the raid. Much smaller than the LCTs, these ships could carry light cars and several infantrymen at the same time.

In preparation for the assault on Dieppe, a flotilla of LCTs was modified to fight the Luftwaffe and to protect the other ships. This model was known as the Landing Craft Flak (LCF), which unlike the LCT, had its deck, normally open to the air, welded shut. These ships also had several anti-aircraft guns and were manned by a crew of approximately 60 sailors.
