Mostly, the luxury of having multiple members in gang suppression units can provide greater flexibility. Officer's safety is automatically ensured because of the built-in "contact and cover" factor. Whenever you are going to make an arrest, make sure that other officers have surrounded the subject to cut off any escape route. In these situations, you can assign tasks to your fellow officers. For instance, you may ask an officer to be a chaser and the other one as the contact officer.
Also, keep someone behind the wheels because there is a possibility that the subject may escape. Also, if an officer is chasing the suspect on foot, it will be useful if the other officer is chasing the suspect on the vehicle. That way, you can exhaust the suspect and make the arrest even if the foot chaser fails to catch the subject.
