I don't know what the big deal is with people insisting on following the "Squad Leader". More often than not the Squad Leader is either a clueless twat or is simply skilled in the fine art of calling in arty. It's just a class name, it doesn't automatically mean that the person playing it is in any way qualified to call the shots.
I much prefer either following someone I know is doing a smart thing, or calling the shots myself as I often do. Imo, "guys, when I start pissing you all off with this whistle, I want you to run into that meatgrinder" doesn't qualify as someone doing a smart thing.
