tomndeb: been reading your C.S. Forester lately, hmm?
:rubs hand together: Now, and without trying to sound insulting to the Marines: the [Marine] Corps opens the door, and the Army steps through.
Marines are experts at amphibious assault; they establish the beach heads. Then the Army rolls through.
Two books by Ralph Zumbro address this very issue, The Iron Cavalry and Tank Sergeant. In Tank Sergeant he discusses and relates through anecdotes from WWI and II Veterans how tanks operated in WWI and II, but also illustrates how they were employed differently by the different branches of the service.
The one that comes to mind is from a Marine, who spent days in high-intensity combat establishing a beach head (at Guadacanal, IIRC) for the Army, and then watched dumbfounded as the Army tankers and infantry slowly but methodically took out the Japanese defenders in one set piece engagement after another.
In quite a few cases, the Marines can be “on the ground” kicking butt before even RDF units like the XVIII Airborne Corp can arrive. They still serve a tactically and strategically functional role in getting their quick and intimidating the hell out of anyone foolish enough to look at them twice until they can be relieved by the Army.
The Marines, being closely linked with the Navy and their Carrier Groups, and all the strategic mobility they provide, are a functional and vital asset in the American military arsenal. On a planet that’s surface is 70% water, the Marines can quite often get somewhere before the Army can, making them indispensible, IMHO.
And this is coming from an ex-Army tread-head.
As far as the Army not being “at the ready” like the Marines: Bullshit.
I spent two years in the 2nd Armored Cavalry Regiment in Bamberg Germany. We were the eyes and ears for VII Corps 24/7/365 (and you can’t be that by sitting in the barracks waiting for the call), and the tip of their lance to boot. We could roll our entire Squadron (essentially a reinforced Battalion) in less than an hour to deploy anywhere in our GDP Zone.
It boils down to mission: when it’s required, the Army can roll just as quickly as any other branch of the military, albeit usually “in theater.”
And I’d bet real money that the Cav was just about as strack as the Marines; coming into it right out of basic, it didn’t bother me as much. But Army Lifers who had never been in a Cav unit before got a very rude awakening to life in the Cav. Fast paced, no-bullshit, move yesterday, save the excuses for weaklings and wimps hoo-rah gung-ho.
Boots and Saddles!
