Produced at the Zeon
Duchy's California Base during the latter weeks of the Universal
Century Era's One Year War, the MSM-10 Zock was one of the last
amphibious mobile suits to be produced - though its form represented
the shift from mobile suits to the new mobile armor concept.
The Zock, one of the
last amphibious mobile suits, was a product of this philosophical
shift. With the thrusters in its armor "skirt" and short,
non-functional feet, the Zock could best be described as a hovering
gun emplacement, capable of covering all angles of attack with
its front-and-back symmetrical design. Three prototype units of
the Zock were constructed. Two were assigned to the North Atlantic's
"Manta Ray" submarine squadron, one of which was lost
when its carrier was sunk by Federal Forces anti-submarine planes.
The last of them serving under Commander Char Aznable's forces
during his assault on the Federation's Jabrow base on 30 November
UC 0079.
