How can you bring a retired person back to active duty? Has this been done before?
Look up flag officer Seldon Hooper.
Back to active duty? Happens all the time. My Dad got nailed for Korea along with a whole lot of other guys who thot they were done———————And BTW, Gen Davy can easily lose one of his stars in retirement if any of this girly stuff is accurate.
If I remember correctly, Generals can be brought back at the needs of the service. He did not resign his commission, he retired.
