After Truman, Maxwell Taylor proposed a reorganization of divisions. The infantry division at that time had three regiments each of three battalions each with three rifle companies.

Pentomic organization stirred the pot. A division would now have five Battle Groups, each with five rifle companies. The new organization did not solve any of the old problems and brought in new ones.
When it was discontinued, the army shifted to three brigades per division, each with three infantry battalions. This is more or less the current organization, with individual variations.
The problem of cohesion has been raised above. There was (and still is) a constant flux of transfers, as men are sent away for training, as officers strive to get in their command time so they can be on the promotion list,
The goal sometimes appears to be like that in Fred Pohl's "The Wizard of Pung's Corners" (
Galaxy, October 1958) where a force of forty-six riflemen requires over 1200 support troops.
