Page "Combined arms" Paragraph 31

Based on this doctrine, many U. S. ground vehicles moved across the landscape alone.

If they encountered an enemy troop or vehicle concentration, they would assume a defensive posture, lay down as much covering fire as they could, designate the targets for requested air and artillery assets.

Within a few minutes, on station aircraft would direct their missions to cover the ground vehicle.

Within a half hour heavy attack forces would concentrate to relieve the isolated vehicle.

In an hour and a half the relieved vehicle would be resupplied.
