In 2009 there were 2,340 armed forces personnel stationed in Dorset including the Royal Armoured Corps at Bovington, Royal Signals at Blandford and the Royal Marines at Poole. The military presence has had a mixed effect on the local economy, bringing additional employment for civilians, but on occasion having a negative impact on the tourist trade, particularly when popular areas are closed for military manoeuvres. Plans to relocate the Royal School of Signals from Blandford to South Wales could result in a loss of up to £74 million GVA for the area.
