and a cool video:

MOBILE TASK FORCES

Mobile Task Forces (MTFs) are elite units composed of personnel drawn from across the Foundation and are mobilized to deal with specific threats or situations that sometimes exceed the operational capacity or expertise of regular field personnel and — as their name suggests — may be relocated between facilities or locations as they are needed. Mobile Task Force personnel represent the "best of the best" of the Foundation.

Mobile Task Forces vary greatly in size, composition, and purpose. A battalion-strength combat-oriented task force trained to deal with highly aggressive anomalous entities may consist of hundreds of troops plus support personnel, vehicles, and equipment and can be deployed in whole or in part to deal with threats across the globe. However, a Mobile Task Force can also be a small, specialized intelligence-gathering or investigative task force that may have fewer than a dozen personnel if that is deemed sufficient to accomplish their goals.

While in the field, task force members often pose as emergency responders, local or federal law enforcement, or military personnel appropriate to the region in which they are operating. Mobile Task Force Commanders can also request the assistance of local field units or personnel stationed at nearby Foundation facilities in order to accomplish their missions.
