In the army, Prince Harry trained to confront death "head on"

 

Prince Harry discusses his struggles with not inhaling gas during Army huddles.

The Due of Sussex recounts in his memoir 'Spare' that he learned a lot about escaping death by confronting death in numerous forms.

"One day, the colour sergeants gathered us outside a redbrick building that had been converted into a CS gas chamber," he writes. They ordered us inside and turned on the gas. We pulled our gas masks off, put them back on and then took them off again. If you weren't quick, you got a mouthful and a lungful."

"But you couldn't always be quick, and that was the point," he continues, "so eventually everyone sucked gas." The drills were intended to be about combat, but they were about death to me. The entire theme of Army training was death. How to avoid it, but also how to confront it."
