I knew that Arthur Alphin and A-Square used to be based out of Indiana, but I did not know that Lee Jurras and SuperVel were located in the Hoosier state as well.
There's something pleasingly symmetrical to my gun nerd eye in that fact.
(Incidentally, LTC Alphin's lecture films from his West Point days are available on the DVD Guns Of War. I highly recommend it. Here is footage of a genial gun nut whose everyday job is to take all kinds of historical guns out on the range and demonstrate their use and historical significance to cadets. He looks like he couldn't be happier if he won the lottery. The footage is rounded out with some classic B&W WWII training films.)
