Could be....
I went AD in '72. USAR in '83. My CSM from '83 is now my daughter's NG CSM! You don't make CSM in less than 10 years, usually between 15-20 years.
For the uninitiated:
AD - Active Duty
USAR - United States Army Reserve
CSM - Command Sergeant Major
NG - National Guard (Unless otherwise stated, Army National Guard)
A good friend will come and bail you out of jail ... but, a true friend will be sitting next to you saying, "Damn...that was fun!"
