If Hitech ever gives us back the AI local resupply for feilds and ports, he could replace the tug and barges with several Liberty ships. Maybe mount some AI guns on them or even have an AI escort destroyer to act as an ack barge and an extension of the port's manned guns so players can see those as a port hanger option. It would probably get abused with someone using land mode to cover the map room or picking off enemy GVs running around on the port. Probably why the trains never had manned gun positions or the trucks had a 50cal position to man for the ride to resupply a field.
You know how we spend all of our time destroying things. Maybe there is room for an inverse way to play this game. Hitech introduces duce and a half's that we can drive supplies with. Then have an alternate type of terrain which has all the citys and strats at 0% when it first comes up. Setup the city's with persistent spawns from the two other countries that they can set tanks in the city all night if they want. The responsibility of each country is to deliver supplies to depots in the city up to so much tonnage per depot to fire up the city auto rebuild of the city and strats. Yes Mable they will try to game it by dropping supplies from 10,000ft in a c47. Put a runway in the city and require c47's to land and kick out the supplies from a full stop like the Berlin airlift.
Then it's business as usual the rest of the time the terrain is up unless a city is reduced to 0%. Then if you want your strats to begin rebuilding again and everything else at a faster rate than happens with strats at 0%. That would be ords and supplies taking 180 minutes...... Run supplies to those depots which are indestructible, opposed to the rest of the city. After the depot tonnage is satisfied, you can keep running supplies to bring up the city to 100% if you want it up faster. Then get rid of running supplies to towns to dictate the outcome of those fights except to get the ack back up. Now you have a strategic reason for running supplies with enemies waiting to whack you that you will need friendlies with jabo or tanks hunting the enemy tanks. The origin field for your supply and defense efforts gets set to uncapturable but, is not a 163 field and gets an exemption for it's availability of supplies. Otherwise greifers would drop the supplies at that uncapturable feild all night on a timer like that old problem with the HQ. Probably need to run the persistent enemy GV spawn in from one of their uncapturable feilds to be fair. And the city can be located a bit more centrally in each country to facilitate all those activities. There are two squads I can think of who would spend the evening trying to hammer down two cities with bomber missions. And Lusche would hunt them in his 152.
Sure it would get boring until your country overall rebuild grinds to a halt. Buzzsaw shows us this will be very egalitarian in terms of accepting reduced global rebuild times and seeing a city like that as a game activity source to fight over not hidden in the backfield near the HQ. Late at night, it's something to go shoot up and have a certain amount of hiding in plain sight everyone wants to do these days. German tanks attacking or defending would be good tools for this especially once you got setup in a hide. Just a bit more dangerous than steal the sheep with worse consequences than getting jailed. And Buzzsaw has shown us that your country can ignore it's city and strats at 0% and still function to capture feilds and kill things if no one wants to bother. But, it will bite to leave it that way from the moment the map first comes up until whenever.
This would force a small arena kind of fight in each country as a persistent thing while not stopping the war winners from capturing feilds and the furballers have two places to check for combat. If a country didn't want to worry about the resupply depot runs after the initial opening of the map, just keep delivering a few boxes of supplies to keep the city above 0% whenever the strat runners take a shot at it or a few tanks kill some buildings.
