“Is that list from the Twilight 2000 RPG?”
Yes. The list is derived from the U.S. Munitions List found in the CFR and a number of arms control regulations and documents. Now, if you are looking for the real thing and don’t mind some Federal scrutiny... :)
The U.S. Army Rock Island Arsenal, Israel Military Industries Ltd., Pakistan industries, and a variety of other places are sources for tank munitions...and inert rounds for tanks and artillery can be found online in a variety of places as collectibles.
