What's the difference.
"IT IS NOT A PENSION!!!! It is Military Retirement Retainer Pay! Just goes to show you that the NYT reporter doesn't know $hit from shinola."
"What's the difference."
Well, for one thing, someone on "retired retainer pay" as the name implies, is on retainer, and can be called back into the active military service of the United States, against their will, for starters. That doesn't quite apply to Joe Sixpack that has a pension from Acme Rubber & Overshoe, Inc., now does it?
