Background information Edit
Dickerson was played by actor Arell Blanton. Dickerson appeared to be among the highest echelons of security officers aboard the Enterprise at that time. It is also possible that he was the ship's chief of security in 2269, a position previously held by Lieutenant Commander Giotto.
Dickerson wore a Starfleet dress uniform reused from a previous episode, where the decorations and braid at the collar represented a lieutenant commander, however, Dickerson was addressed as "lieutenant". (It should be noted, however, that some lieutenants, such as Shelby and Deanna Troi, have occasionally been addressed as "lieutenant").
