Don't get too wrapped up in identifying the "retired military officer". That could just be the cover story that DNC/Kerry used to sell the (known) forged docs to CBS.
Maybe it is as you say a forged source. In that case, I suspect we would indeed hear who it is...
But, again, I doubt it. Too many things from long ago have neatly lined up for Hillary. This particular goof is so utterly spectacular .... unless Kerry is Supposed to Lose.
