Rhino rangers taught to catch poachers

Gripping a semi-automatic rifle in his muscular right hand, anti-poaching instructor Simon Rood berates students for not taking their gun lessons seriously.

"This thing is like your wife, you will treat it with respect," he stresses. "If you do not treat a firearm with respect, you can't be a ranger," he said.

The students, a group of 19 dressed in forest-green fatigues with black military boots, nod their heads to show they understand.
