What’s unsurprising is how strictly gun control is implemented on US military bases and navy ships.
If you live in barracks on-base and own a personal gun, if often has to be stored in the base’s firearm storage. The only people who can walk around armed are MPs or people on their way to/from authorized training. Even if you have a concealed carry permit for the state the base is in, you can’t conceal carry in the base. If you’re on your way to the base’s firing range and stop to get gas at the base’s gas station, you can’t leave your gun in your car while you go into the convenience store at the gas station unless your car is locked in your trunk. Often even a paintball gun has to be stored in the base armory.
Keep in mind these aren’t rules for random civilians. These are the rules for people who have already had to pass extensive firearms training courses.
It’s pretty insane that random untrained civilians have far fewer restrictions on guns than members of the military on a military base.
