There are two kinds of ships: Submarines, and Targets.
I was an undergraduate classmate of Larry Pinsky's at Carnegie Mellon (then Carnegie Tech) in the mid to late 60's Pittsburgh. He graduated in Physics in 1968, and the last I saw (perhaps 1 year ago) he was head of the Physics department at the University of Houston.
We were in ROTC together as well.
He would have been born in the 1946-47 and should be 65 to 66 years old, as I am.
He seemd to been involved in many games beyond Blitzkreig during his time at Carnegie. One story I remember is him discussing the Kofax desert in the Blitzkreig game, named so because it was so sandy - look up old baseball pitchers.
Hope this helps.
And welcome to BGG! Ever go by the nickname "Old Blood & Guts?"
