The Director: The Director is the leader of the unit, usually the one sending operatives on missions. He is also the main strategist, and should be operating a few kilometers away from the actual battleground.
Executive Officer/Team One Leader: The Team One Leader is one of the secondary leaders of the whole unit, and the leader to which Team One answers to. He usually joins the team in their operations.
Tech Support/Hacker: As the team suggests, he hacks into enemy servers to either help in spying, or to destroy a whole server. He shuts down communication systems, as well, and operates different devices that can help in tracking enemies through walls. Though he can help in the field, he is only armed with a pistol.
Snipers: Long-riflemen. Don't go brawling with the enemy head-first, and instead choose to shoot from long ranges, though sometimes, they have to get up close and personal with a few enemies in the case that they are either found, or if they need to clear a good spot for them to snipe from.
Intelligence Officer: Doesn't go to the battlefield, but is smart. He/she usually teams up with the Hacker to gather important intel from the enemy and relay them to the Director.
Negotiator/Medic/Psychologist: In hostage situations, the Negotiator plays an important role in trying to make the enemy surrender, or to weaken their resolve through the use of psychology. If things gets bloody, the Negotiator becomes the Medic after the conflict and treats those who were wounded with first aid.
Shooters: These have the most important job if things get messy. They are the front-liners, basically, and make use of different weapons. They usually come in after the snipers do their work.
Spy: He gathers intelligence as well, but is only deployed if the Hacker and the Intelligence Officer fail to gather intel from hacking into servers and searching files. He goes covert behind enemy lines to gather intel from the enemies themselves, and is a great social engineer. In the battlefield, he can make use of different technologies to find enemy positions with drones and hidden cameras connected to a live feed on a tablet. He is also a stealthy bugger, and can be used to assassinate people.
