First of all: I am in no way disrespecting the USMC, what they do, or who they are.
I know the USMC is a total fighting force (air, land, and sea components) with the mantra that every single one of them no matter what rank, title, job, or task they have is a trained combat infantry Marine. But since they they rely on the USN for transportation anyways, would it not make more sense for:
-Navy to continue to operate the ships the amphibious forces use for transportation / logistic.
-Navy to take over fast jet operations (AV-8B, F/A-18).
-Army to have "marine" divisions" which would deploy as the Marines do currently and operate the vehicles and helicopters.
Now I realize that the Marines have a long and proud tradition in the US. And I know the USMC is not going anywhere anytime soon. However, hypothetically speaking, would the above force utilization make more sense?
I've thought about unified commands (like we've have/had in Canada) where the AF operates anything that flies, and I can see how that type of utilization would not be successful for a force as large and diverse as the US military. But if the US armed forces were completely restructured (without institutional biases), would the USMC remain or would a structure similar to what I have outlined be more efficient?
Looking forward for any thoughts .. and again, I have nothing but respect for the USMC, I am simply curious.
