Hi, I am a Navy Fleet Marine Force Hospital Corpsman. You want my job. What I do for a living first and foremost is being a battlefield/Combat medic. I am trained in first aid, triage, and advanced life saving skills to take care of my marines when we deploy to a combat zone. I also am trained in basic nursing/medicine so that between the times out in combat I can run sick call, do health and wellness checks on my troops and on civilians in the local populace. I personally was involved in the Tsunami relief efforts in Banda Aceh Indonesia in 2004 and in the southern Philippines mudslide in 06 as well. In addition to deployment schedules, I do also from time to time, like now rotate back to the US and work in a hospital clinic (currently on the west coast), during these times you can also apply for different C schools and receive new specialties, anything from X'ray tech, phlebotomy, to physical therapy and psychology. We run every aspect of the hospitals and see patients that are not only active duty, but also retired personnel and family members.
If you have any more questions feel free to email me at any time. I also happen to be a divisional career counselor so I can hook you up with a lot of information to get you started in making your choice on what you would like to be if you choose to join the military.
