my good friend at the time also got in his mind that he wanted to be one of the elite members of the mil. He was super fit and had a strong threshold for pain and was very determined to join up! I got him with religious line of commentary about Jesus wouldn't want him being part of an organized military troop that gets orders to take out whoever, wherever they're told. I said if he could live with that, and having possibly hundreds of kills to his name, go for it. Thankfully, he listened, also. I'm glad you did that for your nephew. You are really giving them right to send you wherever, and you could easily get a lifelong illness, like my brother got from a sand war.
