British infantry squads were made up of 10 men organized around the Bren light machinegun, and consisted of a machinegun group, formed by the second-in-command, machine gunner and loader, and a rifle group made up of 6 riflemen. The squad leader commanded both groups. The infantry uniform was marked by the distinctively shaped Mark II helmet, while the so-called "Battledress" of short wool jacket, leggings and boots was worn by all branches of the army. A denim version of the same battledress was worn in summer months, while leather jerkins were used in winter. Tank crews initially wore the same khaki battledress with the addition of a black beret, but in the later stage of the war this was largely supplanted by coveralls.
