Found this page through some Cold War wargaming site and thought some of you might like to check it out.
Clicking on the year you're interested in loads another page with various formations at battalion, regimental, division and brigade levels
Clicking on one of them loads a PDF with icons representing the various vehicles and other equipment but no names which is a pain in the rear because frankly, I can't tell one Soviet artillery piece from another when it's just a silhouette.
