Long Range Precision Fires seems to me to be a move to move the center of mass away from armor/mech and to artillery to simply pulverize the OpFor where ever it lives in increasingly cost effective ways as the range bands decrease. If I guided RAP arty shell can reach 70 km and cost as much as the shell plus a <$10,000 guidance unit/fuse, then engaging a single 6x6 supply truck with an artillery round suddenly becomes a perfectly cost effective way of doing business. GMLRS pushes that out to 100km+ and $100,000+ for the long range version, but that's still worth a radar or command post at least. PrSM pushes range and price to 500km/$1million, and SM-6 pushes that further out for ~4 million. LRHW is probably 30-40 million, but at that point you're hitting target a couple thousand miles away.
The main feature all of the above need is sufficient ISR to provide targetting data, AI to sort through the wide area target data and identify targets and prioritize them, and further AI to take a list of targets, a list of potential fire sources, and match them up in a range/cost effective manner to produce good effects. I'm specifically very interested in the Project Convergence exercises for this reason. Last year they utilized commercial satellites as well as military ones and apparently the observe to shoot cycle was in minutes or seconds. Obviously that's in a benign test environment, but if a robust, survivable ISR/AI system could be produced to provide fire missions to the Army's LRPS units in an organized way, artillery might decide most engagements.
Picture an armored brigade resting for the night engaged by a battalion of ERCA howitzers upgraded with auto loaders, using GPS ammo and provided with exact vehicle targets as their fire missions (one vehicles = one shell fire mission from one gun). You could fire a round at every armored vehicle in the unit in a minute and then scoot and see what survived.
