FIELD NOTES: Though it bears a remarkable outward resemblance to the Mad Cat, the Mad Cat Mark II is a new creation developed by Clan Diamond Shark. It has all the speed, armor, and firepower indicative of a Clan assault ’Mech, and its Jump Jets give it good agility. When equipped with short-range weapons, the Mad Cat Mark II is good for close-quarter city fighting. When loaded with long-range weapons, it is a fearsome fire-support ’Mech that requires little protection.
