The Marine Corps handles 90 to 95% of all "Peace Time" military actions while subsisting on the hand-me downs from the other branches and a paltry 3% of the Defense Budget. Navy Seal teams get more money for training ammo than the entire Marine Corps.
At the beginning of the 1st Gulf War, the Marines were just getting the M1 Abrahms tanks the Army was swapping out for newer models (before that the Marines were still on old M60 tanks).
In the late 90's (97-98) the Marines were just starting to get the venerable Singars radios. Up till then they were still using post-Vietnam era AN/PRC-77 radios.
Time and time again the Army goes and asks for more men and money, new gear, etc, because they state they cant accomplish the mission with what they have.
And time and time again the Marine Corps happily takes that "old outdated" equipment with fewer men and exceed... There has long been a rivalry between the branches, but maybe its time for the other branches to take a page out of the Corps manual and learn how to do more with less. You could drop military spending by half at least, if not more, by following the Marines lead.
