As a Navy Corpsman I under went:
Navy Recruit Training- 9wks
Basic Hospital Corps School- 14 wks NEC HM 0000
USMC Field Medical Service School (kinda like marine boot for Corpsmen)- 8wks NEC 8404
18months- follow on training at Naval Hospital, worked ER/EMS
Then completed the 72 week Amphib Recon pipeline to earn NEC 8427
Non Stop field training/deployment rotation when I got to Fleet Marine Force
Sea/Shore rotation 5 years out/ 2 years in. Once you are FMF you have a wider range of assignments for Sea Duty than regular Corpsmen/Sailors.
Combat Corpsmen make up less than 10% of the rating so it is a small world and once you go "green side" the rest of the Navy treat you differently.
I went Marine Regs so I wore MC dress and utility uniforms, of course I had to meet the standards for PT and Height/Weight set for the Corps. I earned the right to wear the EGA.
Course after all that I went back in the Army where I had come from.
there have 20+ Corpsmen win the MEDAL serving with the Corps, in Korea 5 of the 7 MOH awarded in actions involving Marine units were awarded to Doc.
Semper Fi,
Doc
