Ok, I'm not going to read this whole thread, I just read the first few posts, but I didn't see it.
In an all out fight, I'd take the MEU, just because of what they are trained to do, which is different from what the Army is trained to do.
Marines are 'expeditionary' because they are the first in. They are extremely
violent. We call them 'dipsticks' sometimes because when you
'dip' them into an area, you can tell how many companies of Army you need to send in depending on the number of Marine casualties.
Marines don't even bother with Geneva conventions... Oh, what, no double-taps after I cross the objective? Screw that, I'm a Marine. I can barely
feed myself, let alone a POW... Kill 'em all.
Army is designed for more sustained operations. Slower, longer, and with regular supply (optimally). Rangers are a different story. They train for
unsustained operations. They go in, secure an airfield, and wait for the MPs to set up a perimeter security, then they move to the rear to refit for
the next mission. I'd still take a company of good Marines over a Ranger company, because if that were actually to happen, you know the Rangers would
get cocky, stroke their own egos, and eventually succumb to the Marines, who know nothing more than to froth at the mouth and devour human flesh
Another thing I think is unfortunate is the fact that just about every combat arms outfit in the Army is better trained for a PKO than they are their
actual mission. Well, that's gonna change. Within 5 years, there won't be a soldier above the rank of PFC that hasn't seen combat, I bet.
Marines know nothing but to kill until all the killin's done. No thinking - killing. No eating, don't have any food - killing. What, out of ammo? Go
take some from that guy you just killed. It doesn't fit? MAKE IT FIT!!!
I'd take the Marines in a drinking contest too, by the way!
