Duane, welcome to the CONSIMWORLD Social Website! Sounds like you are playing some really classic titles! I too was an armor officer--M60 A1 RISE (Passive) for the USMC; retired after nearly 30 years and am currently teaching Army officers in the U.S. Army Command and General Staff College. Love reading history books, too; my problem is I like any and all periods of military history in any domain (land, air, and sea) and scale (strategic, operational, tactical)! Hope you find some groups you enjoy and can contribute to! If not, consider creating some of your own!
