Honor between soldiers/fighters?

[abaris]

When somebody joins the service, they;re ready to do neither.  After a little conditioning, they might do the former - and have completely eliminated any thought of the latter.  Sure it's different.  Soldiers get payed.

My grandfather, who fought at the Eastern Front in WWI always told me he only fired in the air and never once aimed at someone. I believed him when I was a kid. Now I'm not so sure. This was the time of charges after all and I find it hard to imagine that you don't try to fend of attackers by any disposable means if your own life depends on it.
