Check out atcofrontec website for details on what they are looking for. Yes the certs they need. Any type of experience will help you out. The call are the same as anywhere else...alarm calls, medical calls, although they do have an ambulance service there also, the odd structure fire vehicle fire. Not to mention what they do on the air field and the when rocket attacks happen. Lots of the same that any other department would face plus the unusual with being where they are. As for number of calls....its just like anywhere else, some days are busier then others. 24 on 24 off. Plus training. It is a very cool and once in a life time experience. Apply and see what happens. Good luck. You never know until you try.
