My logistical walker would be more multipurpose- Designed to provide battlefield awareness, enemy weakness and warning, and to route supplies to where they need to go, while also calling in air support, resupply, reinforcements, or requests for new orders.

So he'd technically be the player that would do everything but fight on the lines, even though he very well could be more crucial. You know? If there's no air support, then he might launch drones, or cruise missiles on his own walker, and if the enemy suddenly has it, he'd be the one trying to knock them out of the sky with electronic warfare, or call for a retreat, or for a certain unit to get out of the way.
