I agree that there's a continuum between engagements involving complex arrangements of heterogenous specialized combat and support units at one extreme, and engagements involving simple arrangements of homogenous combat units at another.

I agree that the former requires more explicit strategy and more organization than the latter.

I mostly agree that the former requires more discipline and more clarity of purpose than the latter.

I agree that certain tactical and strategic maneuvers (e.g., retreating in good order or attacking in a coordinated fashion) become much easier as you traverse that continuum.

I'm not entirely convinced that "war" doesn't equally well denote positions all along that continuum, but I guess that's a mere dispute over definitions and not particularly interesting.

(nods) OK, fair enough. Thanks for the clarification.
