The Britannian Infantry is a division that consisted of Britannian soldiers who served the Britannian Army. The use of foot-soldiers within the Empire is still fairly unknown, and only a few instances of them being deployed are shown, usually when a Knightmare would be too large to use. When they are, squads of Honorary Britannians and Britannians are likely to be used, as "grunt work", like hunting down rebels in a ghetto. Britannian foot-soldiers are typically outfitted with assault rifles, pistols, body armour, and helmets with electronic visors. They are well trained and very loyal to the Empire. They were also present during Emperor Lelouch's regime. When they're not in their armour, army officers and soldiers are seen to be wearing blue uniforms.
The Britannian Combat Armour is considered to be the most advanced in the world. The armour consist of Gray Jumpsuit, Flak Vest, two Pauldron and a Helmet, the Helmet is seen as the most technologically advanced part of the Armour, the helmet have a built in walkie-talkie, electronic visor which allow them to see in the dark and a gas mask.
