The emergency division emergency service such as Fire Fighting, police work, and EMS. The patrol division sought after security and sanctuary. The patrolled (hence the name) the borders around our base. They also did border security. The combat division actually did the "war". They fought, if needed and used lethal weaponry. If one of the enemies were to come near or on our base, patrol would hold them off until combat arrived. Because there are only 10 people in each division, you could volunteer for a space in the division. I volunteered for a spot in special combat, which basically means that if the combat division wants to invade enemy base(s) I coordinate the attack. They've only had to use me once, but it was the best time I had ever had.
