Troop Academy Building Extended

The Troop Academy Building has been extended to level 15 to allow for an increased promotion queue size and promotion to the new Mercenary Troops. No details have been provided, but I expect you will need to go until level 15 to be able to upgrade to (tier 4) Mercenary Troops. Also you need to complete the Merccenary research first.
