The Duke Of Lancaster's Regiment
French soldiers have joined a British battle group for the first time in history for a live firing exercise in Northumberland.
The sounds of gunshots filled the air at Otterburn Training Area as around 400 soldiers from the 1st Battalion of the Duke of Lancaster’s Regiment teamed up a 120-strong party from two regiments of the Foreign Legion.
They worked together, using mortars and practising real life war scenarios, working as if they were trying to seize a position.
