I'll say this about the 'rivalry:' Marines have a history to be proud of (for the most part, of course), I think all branches should have more in depth basic training, and that knuckleheadedness is indeed a virtue in some combat scenarios. To scare the piss out of the enemy even when greatly outnumbered is impressive and a pure asset.
The Army I refer to revolves around only the combat-oriented sections. I have no respect for POGs in the general Army (Rangers, on the other hand, make badasses of even the cooks, as do Marines). I know for a fact that my training was superior to infantry Marines I came across.
I had a rude awakening when I went to an Appleseed shoot last year regarding standards of Rifle Marksmanship. Turns out that Parris Island Boot Camp and San Diego Boot Camp have completely different standards of marksmanship training.
I was taught basic marksmanship at Parris Island, and fortunately for me it was the better of the two. All kinds of concepts that PI Marines knew innately, like Natural Point of Aim and following though on the trigger until the seer resets, are unknown by SD Marines going back to the early 80's.
Why in the frell would the two Marksmanship Units at Parris Island and San Diego have such divergent results? I dunno, but I don't like it.
If I saw that sort of thing WRT marksmanship, you can bet that the Atlantic Commands and the Pacific Commands likewise have divergent standards for infantry tactics training. I know in 1993 when I was in Marine Combat Training (The 'abbreviated' Infantry School for non-infantry MOSs) we went through a good deal of MOUT (Military Operations in Urban Terrain as we called it) training. Now I know if us Intelligence guys got MOUT training, that the grunts HAD to have gotten a hell of a lot more than we did.
I have been in cooperative missions with them, and they seemed to be lost (in the urban setting, mind you). My Air Force friend went to Israel to train Marines on some urban assault tactics (which worries me, because I know Smith doesn't have the same level of urban training as I, either), and when fired upon, he saw an NCO (E-7, I believe) Marine run screaming.
Well, given that this was an Air Force guy with an Army friend, I'd probably take this war story with a grain of salt. Nevertheless, I'll say that regardless of what branch or unit you are in, there will probably be someone out of the thousands who will not react well the first time they take incoming. You probably know that a single anecdote is not evidence of any kind of general reality.
That is worrisome, and is reminiscent of the Iraqi National Guard troops that accompanied my unit on some patrols in Baghdad. They would actually run while shooting AKs backwards over their heads when fired upon. It is in this regard, the modern combat setting, rather than the Vietnam stuff the Marines thrive on, that I believe the Army can lay some claim to tactical superiority.
Well I know that there has been a major sea change in focus in about the last 2, 2.5 years into heavy urban warfare training. Of course, the Marine budget cannot afford to build all kinds of mock cities, but we do get to use Army facilities from time to time.
I can also point out that Marines are leaving Iraq (which could be seen as a tapout

) of their own volition. LOL, anyway---both branches are still improperly stuck in the 'we'll fight in the woods and mud' mindset, but overall are similar, in infantry terms.
This, I think, is more a question of mission. The Marines have, what, fewer than 1/16th the manpower of the Army? The mission of the Marine Corps is to take ground, and
not to hold it. If we were to follow established doctrine, then the Marines should have left Iraq a long, long time ago, sat offshore, and gotten brought in for the occasional need to recapture a city or some such.
As for surplus stuff....as much hatred as I have developed for the military 'thing' since being in, some of the stuff would be quite useful to keep on hand. I wouldn't list a MOPP suit on my priority list, but a gasmask would be good. Too many nightmarish memories of times in MOPP suits. I remember scarring my bleeding face and being totally unable to see and people passing out from dangerous heat/dehydration levels ....blech, no MOPP suit for me, even if the 'Thrax is on the loose.
Well, is it possible that we will have to deal with VX gas? Maybe, but so remote as to deny belief. What else is a MOPP suit good for then? For one it blocks your scent from tracking dogs. All you have left to worry about is hands, feet, and head. Another $20 for scent-blocker socks, gloves and balaclava, and you can walk right in front of a bloodhound and never leave a scent trail.
(If I ever have to bug out - I hope it's in winter...... heh)
My prized surplus possession is my Marine digital pattern woobie. I remember some people in my barracks being jealous, and my Platoon Sergeant complimenting it and wanting to know where the fuck I got it.

I also have a very large wooded camo pattern tarp with bungie cords. Sounds like shelter for the upcoming shit hits the fan episodes. Other than that, I still have 2 or 3 duffle bags loaded with the military stuff they don't want when you get out, plus a few extras.
I don't know how, but my local Wal-Mart wound up with a bolt of actual copyrighted MARPAT. I bought 12 yards worth, and have been contemplating making custom LBE out of it.
As far as all my stuff, I had tons of stuff when I got out, but I was an idiot. As a short-timer and a hot headed young-un I let myself go a little, and the SSgt at TMO said he wouldn't ship all my stuff home unless I went and got a haircut. I mean, my hair wasn't THAT long. But I refused. Probably lost $8,000 worth of stuff because it never got shipped home, because I refused to get a haircut so the TMO SSgt would ship my stuff home...
Oh well. Grow older and ya learn stuff.
