Personnel from the 1st Regiment, Royal Horse Artillery share a joke during a lull in tempo working on Ex Steel Sabre.

Exercise Steel Sabre: The aim of this huge Royal Artillery live firing exercise was to bring all the components of an effective Artillery group together to train in its core business: delivering firepower on the battlefield.

This included soldiers from different nations and from the Regular and Reserve parts of the British Army employing artillery guns, rockets, mortars, radars and unmanned aerial vehicles on the Otterburn Ranges.
