Hi Jaron,
There is a problem between using an example that is battlefield and the other is a classroom or at best a "duelling" situation. One situation you get to prep and be dressed in "training gear". The other you get body armor, ammo pouches, canteens, helmet, in heavy boots and load bearing vest/harness... of course the description of the load changes the further back in time you go (but the load doesn't). Once you add all that crap, plus the fact that everyone is scrambling for their backup knife or other battlefield debris to be used as a weapon and screaming for their buddies to stab their opponent in the eyes. (Heck I'd yank my helmet off and change his world view with a kevlar transplant to the face and collarbones).
Even if you were not in an "inferior" position with regards to submission fighting, having a guy on top of you is an inferior position on the battlefield when he's got buddies who can stomp on your head or cave it in with a handy implement.
So I think that the ideal groundfighting battlefield skills are those that help you get out of that position and into another, preferably behind a weapon.
That's my two cents.
Tim
