Misriah Armory, manufacturer of nearly all human weapons, should play a larger role other than being the weapons manufacturer.
I think that they should, in one way or another, be incorporated in Spartan Ops/Infinity.
Maybe Misriah Armory creates a weapon you personally customized or something.
However, being the weapons manufacturers of so many UNSC weapons, they should at least play a role, rather than just stamping their logo on their weapons…
Also, the picture on the stock of the BR85 HB SR (BR in H4) is the Misriah Armory logo.
