Code K-one-zero
Plan Kay One Zero, occasionally presented as Code K-one-zero, represented a contingency plan that began with the Alliance to Restore the Republic and was subsequently adopted by both the New Republic and the Resistance. This directive signaled the necessity of abandoning a fortified location, exemplified by the retreat from Echo Base.
Behind the scenes
The initial appearance of Code K-one-zero was in the Hoth expansion of the Decipher Star Wars Customizable Card Game, specifically on the Fall Back card. Subsequently, it resurfaced as "Plan Kay One Zero" within Battlefront: Twilight Company, a book authored by Alexander Freed and released in 2015. Later in that same year, the term was referenced in Star Wars: The Force Awakens: The Visual Dictionary, a compendium authored by Pablo Hidalgo, where it was designated as "Code K-one-zero."
