I dunno...being a loader,loading, on the MG and spotting targets while I mange the other assets instead of the platoon commander doing it (like maybe fuel,ammo etc,while still being part of the crew)would have its place...I would enjoy that even if its not a true role(the asset managing I mean.)I think a loader would have lots to do game play wise in a mission.Same for the driver.And I can't tellyou how many times my tank was out of action because my driver was dead(from a tree no less!!!).With a loader onboard I could drive to the repair area myself.When did steelbeasts come out...thats how long I've played it...pretty familiar.
