Starfleet service career
In 2400, at the age of 19 she entered Starfleet Academy in the same field her father and mother trained in and she passed all of her classes with flying colors and she graduated top of her field.
In 2401, while on board the USS Peterson a Nebula-class ship training the ship was ambushed by a Klingon squadron led by a Klingon Captain that thinks the treaty is a dishonorable way of winning a war.
In the same here she was posted to the USS Jonesboro, a Galaxy-class starship as first officer while on a mission the ship came under attack by a squadron of Klingon warships that caused massive damage to the ship and killed the Captain forcing Commander Martin to take command and get the ship back to the nearest starbase.
In 2409, Captain Martin was taken to her new ship the USS Enterprise-F and was given command of the ship by her father Admiral John Martin, and she got to hand pick her crew for the mission that she was going to be given. (Star Trek: The New Generation)
