EDIT: I'd like to add that this is mostly US-centric. In other countries, doctors probably range from B tier to S tier. As for defense attorneys, I honestly don't know enough about their demographics to determine how many of them are Alan Dershowitz and how many are actual public servants.
They do enforce maritime law and are involved in a defemse capacity in some countries, but I've always looked at them as the guys who rescue people stranded in boats or fallen into water though. Maybe the American Coast Guard is uniquely shit. Personally, if you count as search and rescue you deserve some more love imo.
they are also the boat police kinda sorta some places, but yeah, I think most of what they do is respond to natural disasters, storms, and do rescues along the coast. I'd personally put it somewhere like B or C tier.
