Description:

    Spawns a friendly AA vehicle to protect the airbase from OPFOR air assets, for a short time.
    Activated via a laptop addAction.

    Benefits of doing it this way = dont need an AI vehicle sitting there at all times eating server resources,
    and hands over interactive control to players from server.
