he must have been army, my friends who are currently serving in the army are quite frankly clueless when it comes to the basics of ballistics. I think maybe the army really doesnt emphasize on this subject. Now my buddies that are Marines its a totally different story they know everything I know if not more when it comes to ballistics. Its nice to learn new stuff from my Marine buddies. But its twice as nice to teach my army buddies a little bit about ballistics.
