I think the units need to be on there just because it is the public square now. Each unit will have a PAO anyway so might as well keep that Lt. occupied. Leadership also needs to see how their units are interacting with the world. Because if you are blind to it your junior troops are still on there spreading all sorts of crap. A usual unit response is to ban their troops from social use. Good luck, next tell teens to keep it in their pants and see how that goes. I would much rather have a thick skinned command team engaged in social media. Or stay dumb and end up how the 2/30 Wild Boars of Fort Polk are. Getting dragged and for good reason.
