Moot point, a 9mm and M16s are weapons of war they are issued to soldiers. The Battalion of Howitzers he served in as a soldier are weapons of war.
NG Deployments are not rare, some are sent packing to the Battlefield and some are sent back to home on a discharge for medical or health or civilian job reasons or ability. I don't care to dwell into Waltz's case because it does not speak to his ability.
Some of you have not knowledge of the NG and that is ok. I evaluated unit readiness, trained and advised NG units, I found some more than capable of fighting on a modern day battlefield and capable of completing their mission assignments.
