Improvement Drive Tiers are separate Tank Classes, organized with the characteristics of their Cannon(s).

Tiers are represented in the Class Tree, shown on the picture to the right, as a series of concentric rings containing every Class in the game. It can be displayed in-game by holding the Y key. In the direct center of the Class Tree is the starting tank; or Tier 1, or Level 1. The first ring contains Tier 2 (Level 15) tanks, the second ring contains Tier 3 (Level 30) tanks, and the outermost ring contains Tier 4 (Level 45) tanks. Areas shaded black on the tree indicate an unavailable Upgrade in that tier.
