Traditionally the bombardier tended the vents at the top of breeches, handled the final assembly of ammunition and placed the ammunition in the muzzles for the gunners to fire.
Bombardier (Bdr) and lance bombardier (LBdr or L/Bdr) are used by the British Army in the Royal Artillery and Royal Horse Artillery.
The rank was equivalent to second corporal in the Royal Engineers and Army Ordnance Corps.
In 1920 corporals were abolished in the Royal Artillery; bombardiers became the equivalent and acquired the normal two chevrons.
The rank of lance bombardier originated as acting bombardier, an appointment similar to lance corporal and also indicated by a single chevron.
