once a man has role it seems to unfair to downgrade him/her after they've served my cause so much. I do alternate roles, but who ever has the LMG will develop quicker than anyone else, this seems an unfair experience tree that can be exploited by those playing the game. I agree that your strength should go up if you're carrying the heaviest weapon the platoon has to offer but Gunners arn't famed for their accuracy, and my gunners accuracy skyrockets compared to a rifleman's, or sniper for that matter, I just think the experience tree for infantry is too biased towards heavy infantry as opposed to light role infantry, it needs to be more balenced rather than the players responsability to rotate his squad role.
