"Yeah, so lots of people have"

"Take a life to save a life, that's what we revolve around, I suppose. If there's people trying to do bad stuff to our guys, then we'll take them out of the game, I suppose. The aircraft does what it says on the tin, our job here is to make sure the guys are safe on the ground and if that means shooting someone who is shooting them, then we will do it.
"When you fire, you still get the cordite smell, which is bizarre. The whole floor vibrates and when you fire a missile the whole aircraft shudders a little bit. It's not like any normal helicopter, as you can imagine."
Captain Harry Wales, British Royal Air Force

Nor is it quite like a video game, as we can imagine. Far more exciting. This is the third in line to the British throne. At 29 years of age one might anticipate that having been exposed to a fairly decent education he might be possessed of a little more intelligence in expressing himself. But it is obvious that this young man desperately wants to be "one of the boys", just another British male doing an ugly job for Queen and Country.

He obviously relishes the role, basks in the pleasure of being relaxed and comfortable among others who accept him (on whose terms?), with no pretensions to royal life. And he values both the sharing of professional military duties and the down-time that comes with relaxation on time off from diligently pursuing the path that he and they were trained for, in defending their country's interests.

So, the facile comment "...take a life to save a life..." bypasses the calm admission of having taken part in military exercises extinguishing human life. He is obviously not as discreet as he might be, under the circumstances. There is a juvenile disconnect with the reality of training a lethal weapon against another human being - but there is the separation of distance and that counts for much.

Desensitization is, in any event, the order of the day, as a casual recounting of his skills at precision, noteworthy aim and destruction. He excels, he feels, as a co-pilot gunner and finds the job "a joy ... because I'm one of those people who loves playing PlayStation and Xbox, so with my thumbs I like to think that I'm probably quite useful." Quite, young Harry.
