WWII Marine?
Many of the campaigns were plagued with supply problems. Some wounded Marines died more from lack of water than medical aid. If I remember correctly Tarawa's Marines were supplied with tainted water before they even landed. Anyone who has gone past the typical government rhetoric concerning what the Marines had to endure through the horrific Pacific Campaign would figure that that pood sod was still suffering from his combat experiences. He was one of the few that lived through the madness, but he still perhaps had the nightmares.
A wounded man loses blood, and requires water. Screams of the dying on the battlefield that can't be provided with the water they crave has to haunt anyone who hears the pleas for years, if not life.
I think everyone who votes for his country to go to war should go with the troops, or personally go to support the troops...cooking, carrying WATER, etc. None of this private contractor bs. If a country decides to go to war, then EVERYONE goes.
