Tired of loosing valuable H.I.S.S Tanks to G.I. Joe attacks. Destra challenged his MARS Engineers to come up with a redesigned H.I.S.S. tank that could fire artillery from a long distance. In response to Destro's challenge the MARS Engineers came up with the H.I.S.S Mark V. Using scavenged parts from abandoned G.I. Joe vehicles left during some of their many battles, they combined the high speed of the H.I.S.S. tank the heavy artillery of one of G.I. Joes S.L.A.M. Artillery Cannons. The combination of these two vehicles makes the H.I.S.S. Mark V the deadliest of the H.I.S.S. Series tanks.
