A cap badge, also known as head badge or hat badge, is a badge worn on uniform headgear and distinguishes the wearer's nationality and/or organisation. The wearing of cap badges is a convention commonly found among military and police forces, as well as uniformed civilian groups such as the Boy Scouts, civil defence organisations, ambulance services (e.g. the St. John Ambulance Brigade), customs services, fire services etc. Cap badges are a modern form of heraldry and their design generally incorporates highly symbolic devices. Some badges that contain images of Lions or other cats are sometimes informally referred to as Cat Badges. Instances in military forces British armed forces The British Armed Forces utilise a variety of metal and cloth cap badges on their headdress, generally on caps and berets. They are also worn on Sikh turbans. British Army In the British Army (as well as other Commonwealth armies) each regiment and corps has its own cap badge. The cap badge of the Queen's Royal Lancers is called a motto by those within the regiment, that of the Royal Horse Artillery is known as a cypher and that of the Coldstream Guards, Scots Guards and Irish Guards is known as a cap star. That of the Grenadier Guards is known as the grenade fired proper. The concept of regimental badges appears to have originated with the British Army. The Encyclopædia Britannicas 1911 Edition notes that although branch badges for infantry, cavalry and so on were common to other armies of the time, only the British Army wore distinctive regimental devices. Cap badge variations Plastic cap badges were introduced during the Second World War, when metals became strategic materials. Nowadays many cap badges in the British Army are made of a material called "stay-brite" (anodised aluminium, anodising is an electro-plating process resulting in lightweight shiny badge), this is used because it is cheap, flexible and does not require as much maintenance as brass badges. Regimental cap badges are usually cast as one single piece but in a number of cases they may be cast in different pieces. For instance, the badge of the now amalgamated, The Highlanders (Seaforth, Gordons and Camerons) was cast in two separate pieces: the Queen's Crown and the thistle forming one piece, and the stag's head and scroll with regimental motto forming a second piece (see the first picture above).
