Drill Ground

The Drill Ground is a key building in Last War Survival that houses your troops. You can construct up to four Drill Grounds: the first is built during the tutorial, the second is available at Headquarters level 16, and the third at Headquarters level 21.

Additionally, the Siege to Siege research can unlock a fourth Drill Ground.
