Others have already addressed it as a scam, so I’ll cut straight to the humor. My late Dad got a real one of those letters and wandered next door to talk to the Board about it...I say “next door” because the reserve unit he was XO of at the time had their command offices next door. He was in uniform. And he’d served with somebody on the Board in WWII and Korea. He said they told him not to worry.
thanks
