Also taking notes from the Shagohod from MGS3, while mining my Mobile Suit encyclopedia (yes I have a Mobile Suit encyclopedia!), I'm going to introduce the concept of Mobile Suits but it's going to be more of to explain such creations as the Xamel in Last Blitz of Cobra.

The Acg was the first practical Mobile Suit developed by Cobra but it was designed for excavation and construction, as oppose to combat, with two drill arms and two rock grinder/cutters built into the torso and a laser torch built underneath the mono-eye sensor. Its legs contain jet engines giving it the ability to skate and hover instead of walking which provided test data for the prototype Dom hardsuit.
