If someone were to harvest all of the resource from a field, I expect they would begin consuming stock at a place far away from their commanding area while moving towards it, to make it easier to transport the gathered supplies to their final destination near the center of operations, unless they were in a long march or a rout.
The harvester would, in effect, be constantly moving away from the dessification, and scraping up everything on the way to it’s headquarters. With more than one central location present, the even, row-by-row threshing of the early agriculture becomes more of a “swiss cheese”, “hole vs. hole” model, where the most rapidly expanding hole always wins the cheese inside of the bordering wrapper. The applications for military strategy and maneuvering, as well as agricultural efficiency, are boggling.
My Crypt Fiends flank their own line frustratingly when advancing their positions, in Warcraft III. The units run down the length of the line to reposition, instead of the whole control group expanding slightly outwards in order to accomodate the tighter circle radian arc from clicking attack on a unit that is farther than the unit that was attacked previously (It’s like, successive attacks cause a tighter and tighter curve to the ranged units’ lines, in an unbelievable or quirky manner as compared to living matter).
