Portman

Part of the fourth generation of Knightmare Frames, the RMI-13 Portman is the first amphibious Knightmare to be produced. Much of its outward design is made with hydrodynamics first in mind. In addition to the standard Slash Harkens, the Portman has a set of torpedo launchers mounted in its shoulders, and a hydro jet pack mounted on its back. Though intended to operate primarily underwater, the Portman can also be used on land, though its speed and combat skills are poor in this area, RMI stand for Royal Marine Infantry.
