Die alot easier is preciously they need experience. Thus battle hard Veterans are harder to skill, it's like throwing a blackbelt against a yellow belt in a martial arts tournament. The Blackbelt normally wins because of more experience. Or like World War I, towards the end the casuality rates soared because they were sending 16 15 14 year olds into battle. I would like to see if you could get troopers move up to field commanders with field experience
