This mission can be tricky, so pay close attention and follow it to the letter. Load up a truck and nine heavy combat units aboard the transport and send it on its way. Once you land, construct a Repair Facility near the LZ and call in two more groups of 10 heavy combat units each for reinforcements. It takes three minutes for each of them to arrive, so be patient. While waiting, send the first group to clear out the nearby buildings and open up this area. Also take out the Rocket Tower located west of the LZ.

After the second group arrives, send the first group west along the southern map edge to the western corner. After the third group arrives, send it and the second group across the river via the eastern land bridge. Don't worry about targeting the enemy defenses. Your units attack automatically. As you cross, a convoy of enemy units, including the commander in the Command unit, will travel from the enemy base in the northeast to another base in the northwest before advancing south, where it will try to exit the map.
If possible, attack the convoy during its trip between bases. Otherwise, advance the two groups west along the north bank of the river. When the convoy crosses the river, attack from the north while the first group attacks from the south. Target the Command unit so it can't escape. When it has been destroyed, an Artifact will appear. Recover it and then return to the LZ.
