Rebel Vanguard Troopers are the highly-trained elite Special Operations Force within the Rebel Alliance. Their purpose: to accept
and accomplish missions that even the Alliance High Command deem impossible.
The missions they are selected for are the type of covert, highly-classified 'black ops' missions you won't find written in any mission log... These types of specialized missions include (but are certainly not limited to) demolition, espionage, assassination, reconnaissance, and counter-intelligence.
Wanting to diversity his abilities in his personal campaign to destroy the Empire, Na'Daar enlisted for the arduous Rebel Vanguard training program shortly after the battle of Hoth. Of the more than 50 that enlisted for that program, he was one of only 7 that successfully completed the training. [Several trainees actually died as a direct result of the grueling physical demands of the program.]
Na'Daar promptly earned a promotion to Major upon completion of his Special Ops training.
Being a member of Spec Ops has its privileges; Vanguard troopers have exclusive access to the latest and greatest of advanced weaponry. Na'Daar's current weapons of choice are the Rebus Arms MR-45 heavy assault blaster (nicknamed 'Big Brother') and the customizable MR-94 Urban Assault Rifle.
