Death From Above

You need to intercept and destroy a convoy of vehicles that moves via the only asphalted road on the map. The best way to do this is to use FPV drone on it, near the location with eight apartment blocks. The starting drone with anti-tank ammunition will do too (just need to reload a bit and avoid rushists trying to shoot at you). After you destroy all vehicles, you get the achievment. If you missed one convoy, it's no problem, they will continue moving through that road from time to time until you eventually get it.
