I liked them in AH2, are they banished from AH3? I have a film of what appears to be a resup convoy taken a few weeks ago, but I was in Tu2s at the time and they were barely more than specks. I certainly haven't bumped into any resup convoys while GVing...
Killing trucks was a subtle way to help with a base take and it'd be too bad if trucks and trains were gone forever (+ I think I need to kill a bunch more trains for an achievement lol).
So! Are convoys a thing of the past?
