Of course they are. You are in the army because you want to be in the army, together with all the pris and cons.

You must be ready to kill someone in a country in Africa (pick anything here) because the govt said so. You know this when you join.

You can die there too, and you know that too. This is why I do not particularly care about the military kills in such a war until someone does not celebrate the same way the guy who killed himself serving in mountain rescue, to save someone else.
