This map takes place on the same one as the first part of Chapter 7, with the exception that the northern half is now inaccessible and it's nighttime. Additionally, there are multiple barricades both destructible and indestructible around the map.
Squad E's main force will start around their base camp to the south, while Keigel and Ryan will start to the east, on the other side of the valley. Because of the barricades, units cannot enter each other's area. The Imperial base camp will be in the north, past the first bridge.
We have our next mission
"Engage and eliminate the Imperial forces. The enemy is encamped on the other side of the canyon. You'll be under heavy fire. But before that happens, Ryan and Keigel will break off from us and flank them."
Location: Achtzehn Mountain Trail
Description: Defeat the advancing Imperial tanks by capturing the enemy base camp. Visibility will be poor at night. The operation will end in failure if Ryan or Keigel bite the dust.
"Squad E, you are cleared for deployment. Commence operations."
