Cap Badge - The Honourable Artillery Company The badge of the Honourable Artillery Company consists of a muzzle-loading gun surmounted by a crown and scroll bearing the motto H.A.C'. Below is another scroll that reads "Arma pacis fulcra" (Latin: "Armed Strength for Peace"). The Honourable Artillery Company (HAC) was incorporated by Royal Charter in 1537 by King Henry VIII and is the second oldest military organisation in the world (behind the Vatican's Pontifical Swiss Guard). Regiments, battalions and batteries of the Company have fought with distinction in both World Wars and its current Regiment, which forms part of the Army Reserve, is the oldest surviving regiment in the British Army, and the second most senior in the Army Reserve. Members of the Regiment and Specials are drawn, for the most part, from young men and women working in and around London. Those leaving the active units may become Veteran Members and remain within the fraternity of the Company, which they then serve in a variety of ways. In World War I The HAC raised three infantry battalions and seven artillery batteries. Today the HAC is not part of the Royal Regiment of Artillery, being a separate regiment with its own uniform, insignia and colours. Operationally the regiment forms part of 1st Intelligence Surveillance and Reconnaissance Brigade.
