412th cadian Dawn of war vs The covenant, flood and banished (Halo wars 1 and 2)

[Thelastranger]

The cadian 412th takes the place of the marines onboard of the spirit of fire except Spartan red team.
The aim is for the 412th to fight through both halo wars battles from harvest to installation 00 against the banished.

NOTE: 412th has it's own leman russ tanks, including baneblades, Valkyrie and vulture and the vehicles of the ultimate apocalypse mod
However no titans only conventional vehicles.


Can the 412th win?

Will imperial guard preform better than the marine forces or worse?

[Rogue 9]

The Imperial Guard roflstomps the scenario. With the armored support they bring they far and away outperform UNSC Marines.
