Flame Troop/Pre 1.3

Overview
The Flame Troop is a premium light infantry unit armed with a flamethrower, and is considerably useful for handling massed soldiers. This unit hold only four shots per combat, and can only attack at a range of one row. Their flamethrowers are useful against Animal-type enemies (such as Raptors or Boars), or other infantry units.

Shortly after reaching level 11 and finishing the quest chain relating to Iron Deposits you will be granted two Flame Troops for free.
