Warband determines how many military units you may have at once. Your Warband size can be increased by:
- Constructing military camps (+2 for each):
Training Camp, 
Axe Thrower Camp, 
Shield Bearer Camp, Skirmisher Camp, Archery Range. - Constructing military camps (+1 for each): Dragonkin Altar or if playing as Himminbrjotir Training Camp, Axe Thrower Camp, Shield Bearer Camp.
- if you are playing as Lyngbakr and unlock Endless Tide, the first military lore, each camp adds +3 to the limit instead of +2
- if you are playing as
- upgrading military camps (+1 for each)
- constructing and/or upgrading Defense Towers while following the Guardian path (+1 per basic , +2 per upgraded )
Your Warchief, Berserker, Kaija, Shield Maiden, Signy, Eitria, Brok, Torfin, Andhrimnir, and Mielikki do not count towards the Warband limit.
Your military units count can be higher than your Warband size. You get no penalty for that.(e.g. when you have a maximum of military units and you lose a Training Camp)
