Import and Export
Ports marked on the map will export or import any item you wish depending on the political state of the town that port is in.
To export, drive up to the building in any vehicle marked by the port icon or any similar looking ones at the port. Press 'Y' and choose 'Export All' to recieve money for everything in the vehicle.
To import, drive up to the building, press 'Y' and choose 'Import' to open a menu and choose items to import.
While NATO controls the town, you will only be able to export or import legal items, but all other items including weapons can be exported or imported if the resistance controls the port.
