The Commando is a canceled Inner Sphere Light Mech. It was announced as planned even before the 0.1.0 release, but no renders or images were ever released. It was unknown when and if it was still being developed until it was officially announced canceled on november 1st in 2012.
By the time of the Clans' invasion, the Commando was a nearly 600-year-old design for an early reconnaissance 'Mech. Despite its age, it was still an impressive unit with its SRM6 and SRM4 missile launchers supported by a single Medium Laser. With 4 tons of armor (a half-ton less than the Raven), it could run up to 97 km/h. Variants of the Commando were created even after the invasion, proving the success and popularity of this design.
