I trust on APS this won't devolve into an Army v. Marine squabble, but fun-loving interservice rivalry is certainly welcome.
Americans have a certain amount of respect for their Army, but the Marine Corps, as we all know, has an enviable reputation among all who respect our military. For the pacifists, the compliment is given sideways, with Marines regarded as being somehow more Bloodthirsty Neanderthal than the rest of the evil military-industrial complex. (Or so I presume.) In the latest conflicts, Marines are re-establishing, reinforcing, and rewriting their old legend for new generations to hold in awe. Theirs are the stories of heroism and glory in our current wars and civilians praising the virtues of our military are more likely to be discussing Marines than others.
Now I'm not saying the Marine Corps' suppposed superiority is all public perception, but I think the Corps' image has something to do with their success. By cultivating a legend of the Marine Corps as a tough-as-nails, gung-ho, pain-is-weakness-leaving-the-body, unstoppable, overwhelmingly ferocious fighting force, a certain type of individual is steered toward the Corps and a certain other type selects a different service. Once in the Corps, the legend, the myth, sets a high standard of service and encourages Marines to meet it, to give their all, to be all that they can be. OK, nevermind that last clause. Semper Fi!
My experience in the Army, however, is that the collective ethos is more pragmatic. The past glory of Army units is sometimes lauded, but generally the attitude is one of "let's just all do our jobs as best we can." The Army is trying for the mythos approach with its "Army of One" and Warrior talk, and pathetically with it's silly Army Values dog-tags and wallet cards. I wonder, though, if they shouldn't try harder. I first realized this mythos gap when I went looking for T-shirts with the Army logo, better yet with my MOS, (Infantry, straight leg/mechanized). Businesses like US Cav and Brigade Quartermasters have scads of Marine Corps, Ranger, Green Beret and Airborne merchandise, but not so many Army designs, and precious few for non-airborne infantry. Most of the Army souvenirs are plain and straightforward. I can only conclude that most of my fellow soldiers aren't all that vocal about their pride in the Army - it's no big deal, let's just do our jobs well.
At least that's how it was when I was discharged last year.
