Sirna Kolrami

Sirna Kolrami was a Zakdorn male who was widely regarded as a master strategist by the 24th century.

In late 2365, Starfleet recruited Kolrami to observe a battle simulation between the USS Enterprise (NCC-1701-D) and USS Hathaway and to advise on tactics as Starfleet prepared for an inevitable confrontation with the Borg.
