Intel
Take control of a Heavy Tank and take out the two MG Nests near the first bridge. Order all units into Follow Mode, then drive across the bridge and take out the two MG Towers on the other end. Switch to an Assault Vet, and order all units to attack the incoming Rocket Troopers. Switch back to a Heavy Tank, destroy the two MG Towers, and send your infantry to capture the flag. Use the Missile Vets to shoot down the enemy when it shows up. Drive down the hill to the next flag, and call an attack on the guards. Destroy the four MG Towers nearby, and capture the second flag. Switch control to an Assault Veteran and lead the other units across the next bridge to take out more enemy Rocket Troopers. Use the Heavy Tanks to take out the two MG Towers, and capture the third flag. Lead everyone up the hill, destroy the enemy, Heavy Tanks, and infantry, and head towards the Gold Star.

Upon reaching the center of the large crater, enemy Heavy Tanks and Artillery will appear in an ambush. Eliminate all of the Heavy Tanks and Artillery; keep moving so the Xylvanian s will not be able to hit you, and General Herman's air support will shoot them down. Pick up any dropped Jerry Cans to replenish the Heavy Tank's armor. Once the crater is clear of Xylvanians, head to the next Gold Star. Mission Complete!
