100th (Yeomanry) Regiment Royal Artillery

100 (Yeomanry) Regiment Royal Artillery was part of the Territorial Army and had sub-units throughout the South of England. It had three gun batteries all equipped with the L118 Light Gun. The regiment's original role was British Army of the Rhine (BAOR) emergency reinforcement, emphasised by its transfer into 49 Infantry Brigade under part of 2 Division. Under 'Options for Change', the regiment became a general support unit fitted out with the FH-70 155mm towed howitzer and assigned to 3 Division; in 1999, it was reassigned as a CS (Close Support) Regiment, losing its ability to deploy as a whole unit. Under Army 2020, it was placed in suspended animation.
