He watches the formation, and informs the Road Captain at the next stop of any potential problems within the group.

At the Road Captain's signal, the Tail Gunner changes lanes before the formation, to secure the lane so the formation can move into it.

In the event a motorcycle breaks down and drops out of the formation, the Tail Gunner will pull off with that rider and chase truck if there is one and provide assistance, while the rest of the group continues. Never leave a brother stranded without help.

The tail Gunner should have a cell phone in order to call for a trailer, a mechanic, or Emergency Services, if needed.
