Paramedic in the US wanting to help

Paramedic in the USA wanting to volunteer

I’m 27, and Paramedic in the US. I have been working emergency services for a very aggressive, busy Ambulance company for three years. I also have four years active duty in the Marine corps (infantry).

I want to volunteer and help treat soldiers but have no idea where to start or what I need to do. ANY help please.

If someone can point me in the right direction with another sub or links I’d greatly appreciate it.
