Place Mines on a snowspeeder. When you run out refill your ammo with a gonk droid and place more, then get in and fly towards an AT-AT and crash into it. The mines and the ship will go off and nearly destroy the AT.

NOTE: Be quick with placing the mines because after awhile they will disapear.

Also my 7 year old brother and I always make a supplies base somewhere (usualy ontop of the Outpost or the Bunker) and keep Taun Tauns and Snowspeeders there so later if we guard a command post and want to leave we just walk over to a Snowspeeder.:D

NOTE: Just making this base usualy takes up most of the game time.

getting more mines and laying them down makes ONE of the others blow up

I hope you realized this thread is from 2004 mate
