My name is Austin and I've been an EMT for the past 2 years. I'm considering joining the Coast Guard with the HS rating. Is anyone a HS that could give me some insight to what one does on a day to day basis and what all opportunities are available to someone enlisting with that rating?

Mate, I would love to help you out. But I'd recommend you post over on the CG side. You could go "General" "HS" or "Recruiting" ... They would be happy to assist you.
