Possibly, but I don't really consider Henning a troll; his answers are often quite reasonable and even.
The enemy in our active locations presently (a number of them, anyway) aren't signatories of the Geneva Convention. While we are, of course, the Convention provides no protections to us, nor does it limit our activities against enemies who are not party to the Convention.
I carried a Geneva Convention card identifying my status and requiring compliance with the Convention, for some time. Theyt were withdrawn, particularly in certain operating areas, for several reasons; one of those reasons was that the Convention didn't apply.
The enemy, however, doesn't differentiate between military or civil participants, and contractors have been hit with more losses than the military.
