In the early days OKW had 33% fuel and munitions. The trucks would set up in resource sectors and secure them to bring them up to full output. All three trucks would set up in a resource "chain" so you could grab whatever resources you need. Unfortunately, due to inconsistencies with many maps, the "chain" was often very strong or very weak. Tech was also very different, such as T1 being the 37mm flak and able to produce panthers but that was changed to be more like the other factions' tech progression.
