Modernizing the Army's Heavy Forces

The Army is looking to speed up its heavy forces. Where does the vision leave leg or motorized infantry?

This is the summary of the Army vision for its heavy forces:

The essential takeaways:

• Robotic scouts and better sensors will spot threats earlier and let the manned force advance more boldly.
• Automotive improvements and replacing the slowest vehicle, the Vietnam-vintage M113, will get the whole force moving faster over rough terrain.
• New weapons and protections will let it kill the enemy from longer range and survive bigger hits in return.

These make sense.

But do the tanks get bigger (and heavier) to protect humans? Are humans needed? Do tanks continue to combine crew, sensors, protection, and weapons all in one hull?

I think ground and air drones will operate like clouds around manned tanks. But I'm starting to think that for campaigns against peers that the new tank will need to be a Sherman-like vehicle. Cheap enough to lose in large numbers and simple enough to produce in large numbers. The key for vehicle design will be helping a small crew survive hits that knock out the tanks. And seeing if our automobile plants can handle a conversion to such tanks.

Or will tanks survive in any form? But if not, what will provide mobile protected firepower to enable maneuver on the battlefield? Can we?

And against an enemy with robotic scouts too, can the primary manned combat vehicles take the enemy scouts out? Or will our scouts have to up-armor and up-arm to outfight the enemy scouts? That has been the lesson of light manned recon units when tested in combat. Will that scout arms race undermine the possible theory of cheap and expendable drone scouts? Where is the cross-over point for spending money on upgrading drones versus mass-producing them?

But with enemy heavy forces trying to do the same thing with detecting and killing enemies at longer ranges, how do our many light infantry forces survive in that kind of battlefield sensor-rich environment without the protection the armored forces will have?

Unprotected people and lightly or unprotected vehicles already seem like dead men walking to me. 

So aside from the Army's vision of its heavy forces which is interesting enough, where does the Army see its lighter forces in this vision?
