Strike From Above

Objectives
Use the Signal Flare to call in airstrikes at the northern and southern ends of Frostmane Retreat. Provided item: Signal Flare
 * Attack on Northern Frostmane Retreat
 * Attack on Southern Frostmane Retreat

Description
Delber's technicians have been up day and night helping us prepare for this strike. Aside from building and tuning the personnel launcher, his men have prepared the covert operations air wing for a strike on Frostmane Retreat. They'll be waiting for a signal to begin their strikes.

Take this flare with you, and set it off near the cluster of buildings at the northern end of the village, and the buildings at the southern end of the village. The flying machines will make a quick strike at each site.

Rewards
You will receive: (or  at max level)

Progress
Did you signal the air wing to take out the troll buildings?

Completion
Both you and the air wing performed admirably. There's no way that the Frostmanes will remain here now. All that remains is to begin mopping up the survivors.
