How many military members actually see combat?

During Desert Storm, I went on resupply missions, stood guard, was part of the Quick Re-action Force(QRF). During the move into Iraq, my vehicle broke down and I was left behind and told once I fixed the vehicle to catch up. So much for the belief of "Leaving No Man Behind" During OIF, I was assigned originally to do truck missions as an SSG, but because I got promoted to SFC right before we got in country, I was re- assigned to take over the Sargent of the Guard for FOB Mosul and Later Diamondback, basically nothing or no one came in or on the FOB's without going through one of my checkpoints,When the FOB were mortar I was in that group of Soldiers who went out to try to figure out were it came from so we could pass that information on. During OEF, I was assigned as the Bde Food Service Sgt, which I responsible for helping outdoor Service Warrent Officer, and the Food Service Officer, do whatever we could food service wise to improve life for our Soldiers,.Our Bde CSM wanted to set up a PX, not just a a small little snack shop, but the full thing along with AAFES coming in later, to take over, and I was told to make it happen, so I flew or rode in convoys from FOB to FOB setting this up or making supply runs. Durng this time I also stood in the remembrance ceremony.Showed my respect as I watch young Service members remain being placed on airplanes to go home, don't get me wrong I was honored to stand there, but in the back of my mind, I knew it could have been me or why wasn't it me. So this CRAP about not leaving the FOB means we are equal to the Service members who went out of the FOBs to engage the enemy are not the same is Bullsh_t, we all had missions to do and we did them, these wars affected us all in different way

It is estimated that 3-7% see actual combat was part of an operation. Command, Air, Medical, and logistics are the tail that wags the dog. WWII was somewhat of an exception,

First off, you gave however many people you told this to BOGUS INTEL! Now that I got that off my chest, I can explain this to you based on what I experienced during OIF.
Infantry- SEE COMBAT!!PERIOD!!!!
Truck Driver- A large percent of them got AMBUSHED by INSURGENTS be it by IED, SMALL ARMS, or BOTH! This is due in part to the fact they were transporting various supplies from one base to another.
Medic- Depending on what actual unit a medic is in, If they are with the Infantry for example or any other Combat Arms Unit, THEY'LL SEE COMBAT!!

I was a medic and saw combat. And while in the Air Force

I was a Navy Corpsman and went with the Marines - 1/6 infantry and was in the first Gulf War. If you are a Corpsman there is a high chance you may sent to the Marines which increases your chances of seeing combat. All that stuff about Corpsman being a non combatant goes out the window quickly in a theater of war. I cross trained with the Marines and my platoon. Generalized statements like that aren't a good idea, because I am sure there have been motor transport drivers who have had to respond to enemy fire or avoid an IED.

It takes several soldiers ready and willing to do their jobs, so that a soldier in combat can do their job effectively. Most soldiers don't actually see combat, but the soldier who is in combat wouldn't be able to do their job very long with out the support of all the other soldiers doing their job.

I was an 1141 / Utility, Electrician in the Marine Corps with 1st Tank Bn.
When 1st Tanks was pushed into Kuwait during Desert Storm, I was suddenly an 1811 / Tank Crewman.

The Marine Corps takes the adage; Every Marine is a Rifleman / Every Marine is a Warrior seriously.

Judging from all the responses and my own career in the USN, I would turn the question around and ask - "How often does combat come to the average day-to-day military man of any service, rank, or specialty? And, I ask that fully aware that at sometimes and places the answer would be "often". But, I am also aware (as a Vietnam era veteran) that for the vast majority, the answer would be, "not often at all, if ever."

Well, as a Marine being in the forgotten war, Desert Storm/Desert Shield, i will say that as a Marine you will probably see combat if there is a combat scenario going on. I agree with the comments of some of the senior brother and sisters at arms here. Todays military has the opportunity, so to speak, to see combat irregardless of your job. And that is probably the same in all branches. Hats off to those who serve.

Why is this even an argument for you to have with people? Each service member has the potential of being in combat if they are deployed to a war zone. If they are concerned about seeing combat they need to join another organization.
