I'm still chewing on the Expeditionary Force 21 "guide" and I suddenly realized something.
If the next Commandant follows through and actual pursues this plan then Marine Tank Battalions are an endangered species. If they continue it will be at the MEF or Division but even if they survive they will be drastically cut.
Last numbers I had was a total of 221 Abrams M1A1 Main Battle Tanks in Marine service. I could easily see that number being cut in half.
Additionally left unsaid, but pointed out by many is the fact that sequestration WILL continue and that will affect total end strength. A USMC that totals 150,000 (my early prediction on where we were actually going) will out of necessity mean a much larger air wing and a much diminished Ground Combat Element. EF 21 if actually implemented will change the Marine Corps in ways that will make it unrecognizable to current and former Marines.
Sidenote: I continue to marvel at the fact that with 7 months left in his tenure as Commandant, Amos would drop this bombshell on the Marine Corps. This is legacy building pure and simple.
