Bumpers and wheel wells don't match up at all. Considering the modular design of the Golan and the way it looks without its reactive armor installed I still say that's what it is. Course the Argus and Golan are surely related vehicles anyways as Rafael designed the Golan in cooperation with PVI. Between the USMC & IDF there were supposedly only 60 Golan MRAP's ever built. Once the Corp eliminated it from the competition the remaining units were removed from USMC service. This would explain where they went.
