Does shooting supply convoys accomplish anything?
There was a vbase with all 3 hangars down, I destroyed its entire supply convoy, twice (I'm a dweeb), and they popped like normal. So far as I can tell, the biggest impact "supply convoys" have on the game is when they crash into your gv at 50mph.
No point in shooting them, no point in defending them, kind of like strats.
Besides actually having an effect on hangar rebuild times, I would love it if the trucks would scatter and pull off the road when you dive down to shoot them.
