Broak Vessery was a Human male who served the Galactic Empire as a TIE fighter pilot within the Imperial Navy, achieving the rank of colonel.
After the death of Grand Admiral Thrawn, Broak Vessery, an Imperial Navy pilot, served under the command of Ysanne Isard.
Isard gave Colonel Vessery's Interloper Squadron and [Stranger Squadron](/article/stranger_squadron], both equipped with TIE/D Defender fighters, orders to rescue the New Republic's Rogue Squadron from a trap set by Isard's clone and Prince-Admiral Delak Krennel above Corvis Minor V. After this operation, Vessery expressed disappointment in the deaths of Rogue pilots Khe-Jeen Slee and Lyyr Zatoq, as well as the severe injuries sustained by Wes Janson and Asyr Sei'lar, viewing them as personal failures he should have prevented, despite the extreme difficulty.
Vessery, along with an Imperial flight instructor whose name is unknown, trained the surviving members of Rogue Squadron to operate the Imperial TIE/D Defender, all under Isard's orders. The intent was to infiltrate Krennel's forces with an alliance of former enemies and ultimately defeat the rogue warlord.
Requiem Squadron, led by Wedge Antilles under the alias Antar Roat, successfully infiltrated Krennel's forces and brought down the planetary shields protecting Ciutric. In the wake of Ciutric's liberation and the deaths of Krennel, Isard's clone, and Isard herself, Vessery absconded with two full squadrons of TIE Defenders and their respective pilots.
