Standardized weapons are the way to go, especially for Cobra's forces, realistically it makes the business of supply much easier. For the Joes, I'm a little more lenient. I don't use many Hasbro weapons either, especially the outlandish or stupidly coloured ones (Recoil's baby blue rifle, anyone?).
Thank goodness for Marauder!
