The Unit

The sign at the entrance of the 303rd Logistics building lists "CSM E.L Haney" as the unit's Command Sergeant Major. Eric L. Haney is the author of Inside Delta Force, the book upon which the show is based.

Mack starts out the series with a noticeable scar on the left side of his face. This changes from one episode to the next as the scar disappears.
