With the combination of severe budget cuts, the Army growing increasingly more expeditionary and lethal and possibly 'encroaching' on
the Marine's territory, will
the Marine Corps survive for much longer?
Seems crazy, but seems to be a possibility.
Given that each MEU comes with it's own Infantry battalion ,logistical support, helo squadron, air wing, artillery, special forces, naval assets, light armor, tanks, and a partridge and a pear tree, that's not an advantage we would give up lightly, I would think.
It gives the heavier services time to complete all their recalls, pack up, and go.
Plus, the war powers act gives the President a 90 day window in which he or she can deploy troops without congressional approval. If I had that small a window to accomplish whatever task was at hand, I want the guys who are already there, and don't need to be called up and take a few days or weeks.
