eliminate the tank unit 2
WARNING: whenever you extract a fighting vehicle ( tank, npc, etc) you automatically extract the soldier inside the tank. even if this soldier is an E rank, the game fires your lowest ranked soldier by default. so if you only have S ranks, the game will fire one S rank to make room for this E rank soldier. if this is an issue, then farming vehicles, like tanks, is only possible doing it on stages like mission 30, this is a LOT slower though.
no faster way to farm tanks. go to Eliminate the tank unit 2, run to it, extract, checkpoint, repeat. all you need is the vehicle fulton.
