|Triage Code X|
Triage Code X was a medical code measurement used during the Clone Wars, by medical droids and clone trooper medics. When a trooper was too severely injured, the on-hand medical professional marked them with a red X symbol on their shoulder. This would indicate that the trooper was not expected to survive despite intervention.
In 21 BBY, the units of Sarlacc Battalion A and Sarlacc Battalion B were caught behind enemy lines and required extraction from Dinlo. As Commander Gree was deployed with the Sarlacc Battalions, Commander Gett was deployed in charge of the 41st Elite Corps. Jedi General Etain Tur-Mukan was assigned as the leader of the 41st, leading the extraction to evacuate Jedi General Vaas Ga, Gree, and both Sarlacc Battalions. Upon arrival, the 41st covered while the Battalions boarded the Republic's vessels, which led to the 41st taking on a few casualties.
After retreating from the planet, Tur-Mukan noticed an injured trooper, named Fi, and called for a medic to assist. A medical droid came to her and stated that he had been marked with Triage Code X, and informed her that he was not likely to survive despite intervention. Tur-Mukan remained with Fi until he passed.
