South Africa is home to the vast majority of the world's white rhino population. Out of the 18,000 that roam the country, 1,000 of them were killed by poachers in 2017 alone.

Despite international outrage at the practice, poaching is still a big business, leaving some species on the brink of extinction.

But the efforts to combat the killing are being met with even more violence. 600 park rangers have died in recent years - murdered by the poachers they're trying to stop. The problem's particularly acute in South Africa, where species like elephants and rhino are coming under ever increasing threat.

Now, a group of British Army and Royal Marine veterans are training South African park rangers using lessons from their time on the front line.

We sent The Nine's Christopher Bobyn to South Africa to take part in this anti-poaching training regime.
