Modernization Of Warfare!

How the military changes!


U-boats- Armed submarines

Convoy system-Merchant vessels sailed together

American Expeditionary Force-All military personnels came together

No mans land- No one would enter because they would be killed on sight.

Trench Warfare- Both sides were down in treches and they would either sit till the time got right in order to fire on the other side.
