I think the answer lies in a mix of all three. I know several logistician types who would probably prefer to move such a force MTVR pure, as the vehicle (once uparmored) offers protection, good firepower(even if only using Mk 1eyeball sensors), while it has decent C2 ability with Blue Force Tracker for the convoy commander.

This is in use in Iraq today, and my current complaint with post-2003 Lieutenants is that some might think they can get away with this routine on all battlefields. Big vehs don't offer good "fighting" mobility, and I wouldn't want to be caught in a contact without HMMWVs for more nimble and lower profile support.

For daily support runs in W. Al Anbar, MTVR-pure has made in-roads.
