Traktors and MS-1 are an invaluable standard game asset

ARGO: To see how much of an affect those little tanks have in the forum pissing everyone off, You can imagine how much trouble they can cause to the enemy on the battlefield without even firing a shot.
BTW, plant 2 of those little buggers on both ends of an IS7 and it becomes a very expensive paperweight.
I guess they are invaluable.
