Hey dude, I was in such a situation. The army doesn't give you a choice. I was lucky that I got two weeks of leave.
And when James was on a military mission, he can't just go home as a soldier. There's a word for that when someone does that. "desertion."
And when you're a soldier and you're in the shit with your buddies and the bullets are flying around your ears, you can't just walk away. The stress that a soldier is exposed to in such a situation is enormous. The only thing a soldier can think about is his spouse, family and friends. And then he comes home and sees his wife fucking another woman.
If something like that had happened to us, I wouldn't have needed an axe.
