If someone who's knowledgeable explains "tab vs scroll" and you can't grasp the concept in about 1 minute or less, then I'm dumbfounded and don't know what to say. It isn't an advanced mathematical or scientific concept nor some grand philosophical debate.
As for the state of officers these days, particularly at the O-6 pay grades and higher, too many of them believe they are above the law and/ or are detached from reality. I can't speak to the RCO in question but far too many of his peers are corporate yes men who have a "do as I say and not as I do" mentality. Maybe he did it, maybe he didn't, but the demographics aren't in his favor.
The whole system's broken and every group has their "10%" so given all of the above we shouldn't be shocked. Disappointed, but not surprised.
