If your army contains basic infantry units such as grunts and rocket troopers here is the best option to use your units effectively and efficiently.

  1. Use your grunts to push up the line while staying away from mortars, sentry guns and vehicle bunkers.
  2. Once your grunts pushed the line far enough place rocket troopers behind to clear up the base.
  3. If your first wave did not work wait for your troops to reload and repeat steps one and two.
