Should the Marines be integrated into the Army?

This is an age-old argument, going back before WW2, with one for and one against. The way I look at it, the USMC is a tightly-integrated combined arms operation, which makes it more effective than the Army, which relies on air support from a separate service. Every Marine pilot has to go through the same boot camp as every other Marine, and that creates a fighting spirit that would not exist in the Army. Again, as I see it, if the Marines have to be integrated into the Army, then the Air Force should also be integrated into the Army.
