Strategy:
Your forces are set at the point 1. You must transport the Oil Tankeroid to the point 8. At first, you must obtain enforcements at the point 3. The most difficult problem on this redeployment is two Sentry Guns of Survivors. But you can destroy these towns from cliffs (the point 2) very easy. Then destroy Barrage Craft (point 4) by Weed Killer. The most difficult task is the destruction of three Cannon Towers (point 5, 6 and 7). You must attack directly, therefore manoeuvre carefully. After this, transport your Oil Tankeroid to the Barn and the mission is succesfully finished.
