A male stormtrooper designated MB - 223 served in the Stormtrooper Corps of the Galactic Empire on the planet Lothal . Around five years prior to the Battle of Yavin , MB - 223 and another trooper designated TK - 626 were assigned to patrol an Imperial airfield on Lothal filled with newly produced TIE fighters . He and his comrade completed 108 patrols of the field during the day , and by the time of 109th patrol the pair were patrolling in the dark . During the 109th patrol , TK - 626 alerted MB - 223 to a " shushing " sound coming from some of the TIEs which the pair then investigated . Weapons drawn , they discovered Sabine Wren , a girl in Mandalorian armor , spraying the Starbird emblem onto wing of one of the TIEs . MB - 223 questioned the girl , and when she didn ' t stand down the pair began shooting at her ; however , Wren was able to dodge the shots and began weaving through the TIEs in the field to escape the troopers . During the chase TK - 626 contacted their commander and asked for reinforcements , after which the pair lost Wren , who began taunting them . Reinforcements then arrived and all of the troopers fanned out to find the Mandalorian , before Wren attacked one , drawing them all to her location , which was next to the fighter she had painted her graffiti on . TK - 626 then realized that a graffiti - bomb had been placed in the middle of the Starbird , which then exploded destroying the TIE fighter . MB - 223 and his comrades were knocked to the ground , their armor covered in purple paint . Double Trouble . For their failure to apprehend the graffiti artist Sabine , MB - 223 and TK - 626 were relegated to night patrol duty and were not allowed to rotate aboard a Star Destroyer . Months after his encounter with Sabine , he and TK - 626 were again performing their 109th patrol of the airfield when they encountered Sabine while patrolling the wall on north side , sector nine . Having learnt that her rebel leader Kanan Jarrus was being imprisoned above Mustafar , Sabine and her friends decided to steal a transport from the airfield in order to rescue him . MB - 223 and TK - 626 attempted to shoot Sabine but she dodged their blaster bolts . TK - 626 alerted the other stormtroopers at the airfield who joined the pursuit . Eventually , Sabine leapt onto the fuselage of a TIE fighter . In the midst of the commotion , Sabine ' s rebel friends stole a transport which began taking off from the airfield . Sabine escaped on the transport but before leaving triggered a bomb which destroyed an entire row of TIE fighters . MB - 223 and TK - 626 survived the explosion which also left behind a smoke plume in the shape of the Starbird symbol . Thus , MB - 223 and TK - 626 ' s second attempt to apprehend Sabine ended in ignominy . Equipment . MB - 223 wore a full set of stormtrooper armor and carried an E - 11 blaster rifle . Behind the scenes .
