Soldiers from Hounslow are waging war on poachers in Kenya, where they have been on a training expedition.
Members of the Welsh Guards, who have been based at Hounslow Cavalry Barracks since 2011, recently completed a gruelling training mission in the African country.
They have now switched their focus to tackling the big game poachers targeting endangered species including rhinos, lions and elephants.
Kenya's anti-poaching team consists of just 32 ex-military members tasked with patrolling a vast 60,000 acres of bushland, where illegal hunters are on the prowl for animal ivory, pelts and bones.
Members of the 1st Battalion Welsh Guards passed on some of their experience of dealing with insurgents in Afghanistan to help them in their battle to protect their nation's threatened wildlife.
Sergeant Julian Thomas, of the Welsh Guards, said: "With our experience of coming under armed attack in Afghanistan we've been able to put our training together with their training and aid them massively in the way they conduct business out in the bush."

The Guards have been teaching them skills from dealing with incoming fire to map-reading, allowing them to quickly call in reinforcements.
The anti-poaching unit faces a tough task stopping the poachers, for whom a single rhino horn can fetch £25,000 on the black market.
They work in 12 hour shifts during the darkness against an enemy which is incredibly well trained, often with professional backing and hi-tech equipment.
Sergeant Thomas said: "This is a war on poaching. The anti poaching team heard recently that one of their guys had been killed in the field, and that's something we can instantly relate to, having lost our own comrades in battle, and it hit home to us how serious this job is. It's a big old trade over here and we were shocked by the scale of the problem."
The Welsh Guards will soon return to Hounslow, where they will begin packing up and preparing to leave the barracks on December 8.
They will head to Pirbright, Surrey, and will be replaced by the Irish Guards once building work has been completed at the barracks in Hounslow.
