I didn't follow the fallout of the Chattanooga shootings, while the Navy didn't bring charges that doesn't mean that nothing happened. Here it is a over year later and the news has been extremely quiet since early August 2015.
Your memo on LEO carrying on installation is only relevant if the OP has been an MP with six years of cumulative experience (para 4) in the military. Since the OP is only 18 he wouldn't be able to posses a handgun to carry concealed or otherwise off duty on a Federal installation. That still doesn't change the fact that as a soldier living in the barracks, all privately owned weapons will be stored in the units arms room.
All I can say is military laws don't govern interstate highways, as long as the vehicles stays on those highways that intersect bases. However, pull off the interstate on an installation and get caught with an unregistered firearm and see what happens.
