someones gotta soften up the target area before you send in the ground forces. all branches do their part. The Navy carries the Marines and Aircraft to the Shores, the Airforce ensures we are watched from above with sheer firepower, the marines invade and conquer, and the Army is to profide necessary forces and capabilities....in support of nation security and defense strategies. I always enjoyed the Army more than the Marines, mostly because they get better toys to play with. haha
