The trooper was apart of a unit of 11 troopers, Lock, two pilots, Jedi General Ring-Sol Ambase and Jedi Commander Nuru Kungurama that were deployed to the planet of Kynachi. The ship they were aboard was eventually destroyed, killing a few troopers, with General Ambase becoming captured. Kungurama was able to lead Close-Shave and the other surviving members to destroy a Separatist factory, in the process, they were able to save three clones. After the mission, they were deemed Breakout Squad and proceed to meet with the Chiss Ascendancy, by orders of Supreme Chancellor Sheev Palpatine.
It is possible that Close-Shave may have died, as he does not appear in any other books and it states that the survivors would go on to meet with the Chiss. Close-Shave was not present in these meetings. Either he died, or another undisclosed reason.
