The raid of Mylen was a small battle between the Galactic Fleet and Dr. Nefarious. The Galactic Fleet discovered a small lab on the volcanic world of Mylen. The lab was being run by Dr, Nefarious, and was used to construct new robot models to be used against the organic life forms. Seeing as how this could easily put the war in Dr, Nefarious' favour, the Galactic Fleet sent a company of Colonial Marines to take it out, which would be followed by a full scale invasion of the planet using Galactic Rangers.
