It functions as a flak-gun with radar. The emplacement can be spawned upon unless destroyed. The main advantage to other anti-air emplacements is that the player can see the planes within a five second's notice. The emplacement can take up to four bombs to destroy. There are four emplacements along the factory that make up the targets for the Luftwaffe in Battle of Britain.
