Did the marines really do all the land fighting in the Pacific Front?

The Army was fighting in the Pacific before the Marines even got there. Look at the Philippines and the Bataan Death March (mostly Army). Look at the fighting done in China with volunteers from the Army Air Corps (Flying Tigers), look at the Army fighting in New Guinea. The Army went in with the Marines in every single one of their Island invasions. Marines just look better in the paper than we do.
