The troops of today use other terms. I still use REMF when I want to denigrate somebody and new troops turn to me with a questioning look. I explain what it means and they laugh. Many have told me they were going to start using REMF so as to use something "new."
What goes around, comes around.
REMF was used by the WWII and Korean War types who trained us.
Glad to hear you are still passing it on.
