 On the plaque it is referred to as the "Jack of Queen Anne".The British Army's flag is the Union Jack, but in 1938, a "British Army Non-Ceremonial Flag" was devised, featuring a lion on crossed blades with the St Edward's Crown on a red background.This is not the equivalent of the ensigns of the other armed services but is used at recruiting and military or sporting events, when the army needs to be identified but the reverence and ceremony due to the regimental flags and the Union Jack would be inappropriate.
