He’s got a vest on, which doesn’t look like it has armor in it; I can’t see any MP5 mag pouches; he’s got a pen-thickness scope mounted on it, flashlight, magclamp; and his balaclava is covering his eyes.
I’d rather go in alone that have this ya-hoo cover my six.
I think he has his body armor under the coat—why, I don’t know, but unless he has an unnaturally small head, it looks like he’s wearing some sort of thick torso-covering garment underneath his jacket.
As for the mag pouches, I think that might be what the horizontal pouches on the vest are for. In any event, at least he has two mags clipped together. It’s not like you need a whole lot of ammo/mags to terrorize innoncents (kidding!). However, I can’t imagine that the type of operations the ATF seems to pull (quick raids) would need as much ammo as say a defensive situation.
I can’t comment on the balaclava. I’ve always associated LEOs who wore those with the 3rd world or an otherwise corrupt police force. I seriously doubt he’s wearing it because of the cold.

And the safety of his weapon is off and he's not ready to engage anything.
