>>5213807Mk IV is the Halo Wars armor, yeah. In fact before Halo 4 sets came out with the updated Mk VI armor all the basic Spartans were Mk IVs owing to the toyline starting out as a Halo Wars line. We gradually got variants like Hayabusa, Security, Recon etc but only Mark IV for the standard armor, never any Mk V (or pre-Halo 4 Mk VI for that matter), there's the Mk Vb "Noble Six" variant but it's closer in appearance to ODST.
