Royal Tank Regiment troops engaged in a session of beach cleaning after visiting a local beauty spot for a barbecue and finding rubbish dumped there.
Maj Craig Murphy (RTR) said his troops volunteered to litter pick after seeing officers and senior NCOs roll up their sleeves.
The mission took two-and-a half hours and filled seven one-tonne bags.
“Thankfully, the team at Merrion Camp allowed us to use their cable for dragging bags up the cliff,” the officer told Soldier.
