What we support and defend

[Ken White]

The Marines are just a duplicate Army...It will be the same thing and will fulfill the same function.

I dunno about the un-american or the Chicken Hawk bit but that comment is quite ill informed with respect to what Marines are and do. And can do -- legally under US Law and International norms. There's also a significant difference in support, equipment, training and capabilities. Successive Congresses have expanded the post WW II Marine Corps of 100K to its current size for some good (and bad...) reasons.

There's also a reason they get to have and keep their own fixed wing combat aviation elements, something the Army would dearly like to have but does not.

Yet again, you need to do more research and think harder. This stuff isn't nearly as simple as you seem to wish it to be...
