Plainly it appears "Medevac" and "CSAR" mean the same to Sans....despite their being two entirely different concepts. The UH-60Q is a Medevac aircraft outfitted with an AirMethods designed Medical interior....but based upon the UH-60M airframe. The CSAR variant is the Pavehawk equipped with lots of different avionics and in-flight refueling gear.
Two very different helicopters for two very different missions.
