Ya so this has crossed my mind several times... unfortunately I think it’s a band aid to an underlying issue.
HSM definitely does not have an identity crisis, but if you really hate HSC/helos, yeah it probably won't be much better. I've done Arctic ASW in HSM...it wasn't The Hunt for Red October or anything. Rad port calls though.
Like DanMa said, there are a ton of opportunities outside of flying the Navy too if you want to do something else and stay in. Another one that doesn't get talked about a lot is LEP. Free law school and you're getting paid.
