Our big green style is an achievement in the Sergeant Johnson DLC for Halo Wars 2. This achievement is obtained when a player wins 3 matches with the leader Sergeant Johnson in either Multiplayer, Skirmish or Blitz.
- The title of the achievement could be a reference to a quote from Avery Johnson, saying "You had your chance to be afraid before you joined my beloved Corps. But to guide you back to the true path, I brought this motivational device. Our big green style cannot be defeated!".
