Indeed, without defense it's a milker. It needs ack AND ownership. Ownership would mean fighter cover, when possible. Why not tie it to resupply? We could have supply depots linked to the availability of field supplies at the bases.
That's a good idea too. Ownership yes... but control? ...Hmmm... not sure on that one. If teams could control the convoys, they would either be used as extra firepower for amphib assaults, or they would get sent off to the corners of the map to be hidden where no one can get to them to attack them. Neither of which is very realistic at all.
Tying them to resupply would be a good idea, but that would mean a complete redo of the current supply system.
