why? the only people that need to be aware of that are the leaders in the military - officers and upper command. They give the orders and the people in basic training/boot camp have the job of following orders, nothing else.
because the media loves to downplay the progress soldiers have made in the middle east. You rarely hear of schools being built or children being rescued, but i have many friends and family in the army who claim that these things happen more than "explosions".
