Running until April 15, the exercise will see the army, navy and air force come together for large-scale training exercises on land and at sea across the region.

The operation runs each spring and autumn in the hills and coastline of Galloway, which lends itself perfectly for a training environment.

An MOD spokesman said: “There is likely to be a substantial amount of fixed-wing and helicopter flying, particularly in the vicinity of West Freugh and Castle Kennedy airfields, Braid Fell, the Mull of Galloway, Fell of Carleton, Galloway Forest, Dalbeattie and surrounding area.
