Not bad ideas RedAce. The reason I don't include the quantities of ammunitions one class gets is because I think that should depend on the Game Options (Hopefully they will be customizable like in HALO 3) for Multi-Player and the scenario of the Single-Player. I mainly introduced Marine classes for those who did not want to make their own and they were each examples of what you could have. Also on the Personal Weapons. There are reasons I have them. I am not saying they should be in game but just a fun fact for fans. All those weapons were in the film.
The Smart Gun was based off of the MG-42 the Pulse Rifle off the Thompson SMG, the M16A1, Colt Commando and SA80 were all on the gun racks in the film. Plus I was thinking if Hicks had his Shot Gun why couldn't other Marines have personal weapons of their own.
