> Instead, I imagine that supplies will be brought to the front lines via self-driving vehicles watched over by armed drones that are programmed to destroy anything that tries to interfere with the supply convoy. You only need to wreck the lead vehicle in a convoy to stop those behind making any progress. A high-tech adversary could do this by a deep precision strike, and a low-tech enemy could simply emplace some mines or IEDs (remotely triggered).
