During the Second World War, the War Office used a site near Tregaron for training exercises. Its continued use for training exercises following the war was the subject of protest by Plaid Cymru which also challenged the UK government's continued military conscription in peacetime. Other locations in Wales used for training exercises included Preseli Hills and Trawsfynydd.
