There are different levels of security clearances and that would be a factor in arms supply,I would hope. While I learned how to shoot weapons, I never had experience with their inventory. From what I saw with government inventory you had to be somewhat trustworthy, but I am sure that varies.Personally, I maintained tows for submarines and my CPO would put a knife up to my face and arm and threaten my life while I was on the main tow controls, endangering both vessels should my arm possibly move and the consequent line slag cause the hulls to come into contact and puncture each other possibly bringing both vessels down being connected by multiple lines. That is my experience and why I am so adamant about change in military culture so women are not harassed and never have their lives at risk for simply existing in the military. It doesn't seem like much has changed. I served decades ago. You sought out your own protection back then. Changes were supposed to have been made. It has in word, but not in practice and there is much variation in different groups, it is a leadership thing, a culture and subculture thing. Some are more advanced than others, some do more than just lip service. I think a troop looks at what leadership will tolerate and look away from, then goes on from there. Your problem troops will go the limit with what they can get away with and influence others with borderline behavior. If one sees another getting away with it, they will be pressed to follow suit. Some troops come from bad childhood experiences where boundaries and rules didn't exist or protect them, so they are inclined to test limits and repeat abuses. That is why the military needs to have uniform rules, regulations and enforcement and above all absolutely the best leadership possible because that it where it begins and ends. Good leadership really isn't that hard, it's out there, there are just no consequences when it isn't.
All the protections in the world can be put down on a piece of paper but if leadership wants to ignore it, it's worthless.
