Dune2000 - Harkonnen Mission 9 Version 1 Hard - tech 3

unit and I think this mission need only Combat Tanks to complete. I tried and succeed , but it took too long time because I am afraid to attack and cant control units well. The position of construction yard is very important. No Infantry, no Light Vehicles even no Outpost, only need Combat Tanks and Repair Pad and Wall to win!
