Brin was originally a military scientist working with Special Operations Detachment 13, a research and development team designing next-generation remote vehicles for the SGB. As Russia's military situation became desperate near the end of the war, her unit was reassigned to front-line duties, and they continued to serve as a reconnaissance and hunter-killer detachment targeting rebels and deserters around Central Russia. Her unit is equipped with TU-3 Combat Drones and a handful of recon variants.
