For now, the Ukrainians must resupply front-line troops on foot or, at best, using motorcycles, all-terrain buggies or pickup trucks, rather than Western-supplied armored vehicles, which attract massive fire as soon as they appear on the battlefield.
Hmm. If that's true, I wonder if it's possible to put a Bradley-looking shell atop a remote-controlled pickup truck and drive it around the battlefield to draw fire off other things.
Maybe put some light armor over the engine compartment to help make it a bit more survivable.
