I'm completely against the idea. It is none of my Commanders fucking business what tools I legally own and possess outside of work.
They don't get to decide what kind of car I drive or when I get to drive it -- and cars aren't even a Constitutional (and SCOTUS-reaffirmed) personal right. Thinking someone might be at risk of suicide is not in any way an excuse for carte blanche authorization for a Commander to pre-emptively remove one of their natural God-given rights.
It is shameful that a 28-year Army Medical Corps officer thinks that treatment of a symptom (ergo, access to firearms) is in any way an effective treatment for what is absolutely a tragedy and an epidemic (military suicides). How about you "medical professionals" use some of that education you have to figure out the actual root cause and treat that instead?
Flight Doc: "Captain, I'm aware that you are seeing me complaining of massive bleeding from your hand being cut off, but instead of actually treating the amputation, we are going to tape your mouth shut so you cannot scream in pain and so you won't bother any of your coworkers with your screams. Come on back in a week and we'll see how you are doing."
