War, (huh), what is it good for....? Not getting type 2 diabetes with the rest of Generation XL.
Sorry but got to say as another ex Regular, that whilst there is a higher chance of getting hurt, it's also a generally much healthier lifestyle than rusting to death in an office, wearing a suit from George, hoping that you'll get a payrise one day.
Great experiences, hard work and some wonderful friendships are some of the many upsides. I was always hugely proud of the way that some of the young men that worked for me developed and showed emotional maturity, judgement and humility (along with getting shitfaced, stealing stuff and generally causing bother).
At the end of the day, there is a level of personal sacrifice, but I also learnt to ski, freefall, dive and kayak, plus got to blow things up, all of which set me up to manage 1500 people doing the same thing.
If he's going to do it anyway, encourage him to make the most of every opportunity, even if it doesn't quite fit with your expectations. (or get him that application form for the desk job at the Spar)
