Gunfire blasts out across a battlefield as a reservist from The Royal Irish Regiment provides fire support in the latest British Army footage showing soldiers in action.
Reservists are seen opening fire across the moorland grasses at Otterburn Train Area, as green smoke rises.
One reservist with the 2nd Battalion, The Royal Irish Regiment, makes a quick re-supply of ammunition before he is back in action firing rounds.
It's a test of the unit's battle skills, amid shouts of command over the blasts of gunfire.
The action is captured in a video clip posted on social media from the British Army's Twitter page.
Other reservists are seen in the background making their advance in testing conditions at the annual training exercise, in the military area on the Northumberland and Scottish borders.
It follows an earlier video clip posted online showing reservists from the 2nd Battalion The Royal Irish Regiment (2 R IRISH) providing rounds of covering fire.
Many soldiers from across the regiments train on the Otterburn ranges, which consist of about 22,900 hectares of MoD-owned land and are an ideal space for them to hone their combat tactics, as the second largest firing range in the UK.
The Otterburn Training Area gives the regiment the chance to carry out covering fire tactics and is the only place in the UK where both AS-90 artillery and multiple launch rocket systems can be fired on exercise.
The Royal Irish Regiment and the Army Reserve Isle of Man have been carrying out live platoon attacks, with live-firing phases, during annual training exercises at Otterburn in over the last few weeks, with updates posted on the British Army Twitter account as they test out their battlefield skills.
Presenters with Forces Radio BFBS have been keeping up-to-date with the reservists during the training exercise.
A military presence has existed in this part of Britain as far back as the Roman Empire in the first and second centuries AD.
It's been used by the British military since 1911, however, when the War Office bought 7,690 hectares of land.
The artillery ranges have been extended since the Second World War.
