Arkforce was an ad hoc formation of the British Expeditionary Force during the Battle of France in 1940.

The 1st Aberdeenshire Artillery Volunteers was a part-time unit of the British Army raised in Aberdeenshire and neighbouring counties in Scotland in 1860. Its successor units served with 51st (Highland) Division through many of the major battles on the Western Front during the First World War. In the Second World War one of its regiments escaped the surrender of the 51st (Highland) Division in 1940 and went on to serve as heavy artillery in the Italian Campaign. The other regiment served with the reconstituted division at Alamein, in Sicily, Normandy and through North West Europe to the Rhine Crossing and beyond. It served on in the Territorial Army until 1967.
