Republic Mobile Surgical Unit
this was the name given to the field hospitals that were established by the Grand Army of the Republic, during the Clone Wars. Each RMSU - Rimsoo, for short - was staffed by military officers, surgeons, medics, nurses, and their supporting personnel, creating a complete hospital location that could be moved close to a battlefront. The primary mission of each RMSU was to patch up the Republic's casualties of battle, in an effort to keep attrition to a minimum in the face of the massive and easy-to-replace troops of battle droids that fought for the Confederacy of Independent Systems. As the name suggested, each RMSU could be packed up and ready to move within an hour's notice, in case the tide of the battle indicated the unit's current position might be overrun.
