of Gurkhas in Number 2 dress): Centre front or between left eye and left ear. Soldiers of the Gloucestershire Regiment and subsequently the Royal Gloucestershire, Berkshire and Wiltshire Regiment wore a cap badge on both the front and the rear of their headdress, a tradition maintained by soldiers in The Rifles when in service dress. The back badge is unique in the British Army and was awarded to the 28th Regiment of Foot for their actions at the Battle of Alexandria in 1801. Additional items that reflect a regiment's historical accomplishments, such as backing cloth and hackles, may be worn behind the cap badge. In Scottish regiments, for instance, it is a tradition for soldiers to wear their cap badges on a small square piece of their regimental tartans. Officer cadets may wear a small white backing behind their badges. Members of arms such as the Adjutant General's Corps and Royal Electrical and Mechanical Engineers serving on attachment to other units often wear that regiment's beret or headdress but with their own Corps cap badge.

On forage caps the paper petals are fitted under the left hand chin strap button.

Distinct cap badges identify members' personnel branch or, in the case of infantry and armoured soldiers, regimental affiliation. Some units further differentiate non-commissioned members from officers by cap badge material (for example, artillery officers wear gold-wire embroidered cloth instead of brass, Lord Strathcona's Horse officers wear silver rather than brass).
