You may find helpful to recognize the different Tiers of Troops in an incoming attack. This will help you build a defense strategy.
Each Troop has its own Type and Tier. The four different Types are: Supply, Mounted, Foot, and Ranged.
Each Type has its own strengths and weaknesses.
Supply Troops do not attack and are used to move Resources.
The higher the Tier, the higher the Attack, Life and Speed. Higher Tier Troops also have higher upkeep and account for more Might.
