Re: John Doe senior Enterprise officers in "The Enterprise Incident"
Memory Beta lists various security chiefs from the novel continuity. The only recurring character is one Ingrit Thomson, an unlikely match for the man (?) in red seen here... I don't recognize the two chiefs whose entries remain to be written, Cruz or Kinitz.
In "Mirror, Mirror" Marla makes a reference of taking her chances with an unseen "Commander Kenno" so this might be the name of the redshirt commander we are looking for.
The command division officer seems to be of hispanic origin, so I'd think "Cruz" could qualify as a credible name.
