As you progress you can unlock different types of troops/units. Each type serves a specific purpose on the battlefield.
  • Infantry
  • Ranged
  • Mounted
  • Siege Machines
Troops/Units also come in tiers (from the weakest Tier 1, to the strongest Tier 3). You can tell them apart by the color of their icon border:
  • Bronze for Tier 1
  • Silver for Tier 2
  • Gold for Tier 3
Certain Troops/Units fit in better with specific Champions, depending on each Champion's skills.
 
Make sure to open the information page for each Troop/Unit to read their description and review their stats, so you can understand their pros and cons and make good use of them.
 
Troop/Unit base stats can be improved by researching further in the "Combat" research tree in the Academy.
