Iron Will
"Mitigates damage taken by nearby troops for a duration."


  • Iron Will is a Hero Ability that can be used by Sgt. Brick in attacks.
  • It creates a large area of effect centered on the hero that reduces the damage that your troops take for a short period of time.
  • Each use costs 12 more Energy than the previous one, with a starting cost of 6 Gunboat Energy.

Offensive Strategy

  • It is best to save this ability a few seconds before your troops are approaching the part of the base with the bulk of the Defensive Buildings to ensure that you get the most value out of the ability since its energy cost increases drastically after each use.
  • Use it to reduce damage from high damage defenses like the Boom Cannon. It could mean a difference of a few hits, buying you the time to destroy it.
    • When using massed infantry, however, it is best to save it for splash damage defenses because Cannons and Boom Cannons will still destroy them in one shot even with the damage reduction.
  • It can be used to help weaker troops like Riflemen and Zookas pass through Mines with less damage, as well as make them more resistant to Machine Guns and Flamethrowers.


  • This Hero Ability shares the same name with an Achievement.
  • The icon of this ability has a Sergeant's insignia on it, indicating its user's Sergeant rank. The shield and the down-pointing chevrons indicate reduction of damage.
