• Flakpanzer IV Ostwind
  The Flakpanzer IV Ostwind can be deployed to the battlefield. This unit is effective against infantry and aircraft.
• 105mm Howitzer Barrage
  A barrage of 105mm artillery shells will be fired at the target location. The number of shells fired depends on your current stored munitions.
