re: Which War Would Result In The Most Severe PTSD For Soldiers?

Just read through the thread. Yes, WWI is by far the worst war in military history. The generals often get bad reps for how the battles were fought, but they were old school generals fighting a mechanized war. The communication or lack-thereof cause offenses to stall once the objective was reached only to be counter attacked. They didn't know how to fight on a new battlefield. So the men essentially became science experiments. The only country that figured out how the new style of warfare would be fought were the Germans. Artillery barrages that lasted for days, the tunneling that the sides would dig in order to set off a mine underneath the other side's trenches. Gas attacks, no man's land and the advent of the machine gun. And like others have said, modern combat with not modern medicine.

Now, the Pacific Theater and Eastern Front were horrible in their own right. Eastern Front was worse for civilians, obviously. No telling how many rapes happened then. And think about Leningrad, the siege lasted from 1941-1944, people turned to canibalism. But the battles in the Pacific were probably much tougher.

Chosin Reservoir in Korea was beyond imaginable as well.

Eta: If you have a chance, read the book "The Last Stand of Fox Company" it's on a company of Marines that held the route open for our troops to get out of the Chosin Reservoir. One company took on multiple regiments of Chinese forces. Toughest sons of bitches ever in my opinion.
