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.
