Jamie graduated at the top of her Starfleet class. Her nickname was alternatively "ice" or "booklegs" as she was often only seen as a pair of legs walking under a pile of books, technical manuals and datadisks.
War with the Dominion loomed on the horizon and she chose the service that would see the most action the fastest, Shadow Ops. She served aboard the USS Fearless from 2374-2375 under Captain Sortha, where she was promoted from ensign to Lt. Junior Grade.
She accepted a transfer to the USS Vincennes as tactical chief in 2375, leaving Shadow Operations to return to regular duty. She served on the Vincennes with distinction, having fought in 12 seperate battles against the Dominion. She achieved one of the highest kill ratios there, scoring 18 confirmed kills. This distinction earned her a promotion to full lieutenant in mid-2376...just before the Vincennes was destroyed in battle.
Jamie was rescued from the debris of the Vincennes by the USS Ticonderoga, a Shadow Operations ship. Being back among SO prompted her to ask to stay. Admiral Sorvek reactivated her security clearnance and returned her to active duty in Shadow Ops...assigning her a tactical officer on Ticonderoga.
*Historical Note*: Jamie Marcus is the great-granddaughter of the legendary Captain James Tiberius Kirk. Although the details of her lineage are vague, it is confirmed that Kirk and Dr. Carol Marcus had another child together (Jamie's grandmother) after David Marcus.
