The Nikardun Destiny hegemony, under the leadership of General Yiv, employed the military rank of tactical commander. Individuals holding this rank were privy to Yiv's strategic intentions. In approximately 19 BBY, Qilori, a Pathfinder navigator and operative of Yiv's, inquired of the general about his strategy for capturing the Chiss Senior Captain Thrawn. Yiv responded by questioning Qilori's potential promotion to tactical commander, which led the navigator to offer an apology.
This rank made its appearance in Thrawn Ascendancy: Chaos Rising, a 2020 novel and the initial installment of The Ascendancy Trilogy by Timothy Zahn.
