Is it possible to serve in multiple branches of the military ?

USMC 99-04
US Army 2005- Present

At(multiple branches) the same time? No. MOS jumps are possible, Having 2 MOS's at the same time is not, unless they have change things recently.

AFTER you get out of one you can Join anther one

Yes, I served 6 years in the Marines and 19 in the Army. The Marines have the hardest initial training, Boot Camp. Therefore, since I had already completed Marine Boot Camp I did not have to attend Army Basic Training.
However, if you were to go from the Army, Airforce, or Navy to the Marines, then you would be required to go through Marine Boot Camp.
The best thing to do is to complete a contract (usually 2 to 6 years) with one branch of service then join another branch as soon as possible. If you wait
Too long you will likely lose motivation to re-join and your training may expire, meaning that you would have to be re-trained. Honestly, after serving in the Marines, the other branches will seem easy. The Marines really are the hardest to get into and instill the highest level of discipline.

I served in the Army and later switched to the Sir Force, since I, along with a few other Special Forces trained troops, were going to be "ON-LOAN" to them for an extended period of time and they could pay us more pay additives and provide us with better housing, if we became a part of the Para-Rescue group. We were there to address a specific internal threat that grew in to a major problem for our Pilots and their safety. The Air Force is where I would go and stay if I were making it a career. They just provide much nicer goodies for their troops and if you listen to one thing, get your degree while you are on active duty, if possible. I did, but, it took me much longer than most, because, I never knew where I would wake up the next morning.

I miss that youthful excitement and that desire to blaze one's own path. I would never want too, nor would I try to take that away from you; however, I will tell you, so that when that day comes you don't feel like you failed, life is going to throw you some curve balls. Many of the people you believe will always be there for you will disappear, especially, if you need them to sacrifice a little to help you. You're going to be taken advantage of and some will take yrars to recover from. Most of all, you're going to find that people, as a whole are not worth the energy, your health, nor the emotions you will waste on them. That's the hardest thing to reconcile, as one passes from a young person, to a cautiously optimistic mature adult. Adderall, we serve for those people who share our country and for those who can't defend themselves or to make an entity pay for harming a defenseless person or for threatening or harming our people. We don't serve to preserve material things, because, it's the people who make it what it is and worth sacrificing everything, even though you don't know the vast majority of them. I have had to refocus my mind on the ones I know and love and work for them.

Just enjoy your youth; never compromise your integrity, because, you'll never get it back; if you want to sample other branches, once you focus your unwaivering attention on those you are currently serving with and have fulfilled your enlistment, go for it. Just, remember that one thing that I suggested you do, above all others, get a degree. There's too many locked doors that only a degree will open, these days and life changes. You could find yourself out of the service, even though you wanted to continue to serve. You have to have that contingency.

Best wishes to you and PLEASE, DO NOT SELL YOUR SOUL TO GAIN FAVOR WITH SENIOR
NCO's or Officers. I saw it happen to some of our support prople and they all regretted it and some found themself caught up in a mess. If you can't get it by busting your ass, then leave it on the table for someone else and you'll always be respected, even by those who will try to take your integrity.

Lastly, if you don't get chills when you see that flag being raised, you need to consider another career.

HOO-RAH!

I served in the Army National Guard and Air National Guard as enlisted and then the Navy as a commissioned officer. It's not unusual for enlisted to go to another service once they've served their obligation but it depends what the needs and requirements are of the next service you are considering. You may actually be reduced in rank a grade if you transfer to another service. If you really want to make a service change, be the best soldier you can and give it a chance as you may chnage your mind and stay in the Army. If you really want to change wait until maybe the last year of your enlistment and talk to another service's recruiter and determine if you really want to make a change.

Sure is possible. If it's what you aspire to do, then do it. It takes a little time in the service you're in and a certain level of knowledge in your field but once you've got that, you can switch. Just keep focused on your goal and it'll happen, I have several friends that have served in multiple branches.

Air Force then Army Guard

Yes it is. I enlisted in the Army National Guard in 1987, then transferred tobactive US Navy in 1989.

Yeah, started out as an 11E20 senior rifleman then went navy for 14 years, became an 11E30 SSG (Tank Commander M60's) then back to Navy to retire. It can be done and passing MOS skill tests as an SSG was not that difficult for me. A lot of specialties are the same essentially from branch to branch, but just have a different name. Go for it.

I started out in the Corps and Aviation was getting over strength and was told to become a grunt 0311 or get out; I crossed over into the Army Aviation and continued for another 17 years

Start with the USAF they are the most picky,The Army is gruelling and hard, I suspect the Marines are close,HOWEVER the NAVY has an EXCELLENT education system A LOT easier basic than those two as well. ...however the AIR FORCE won't take anyone else in their ranks as I recall.

I did it 15 yrs in the Marine Corps and 15 yrs in the Army.

What everyone has said is all good but some branches will not take you if you were a marine

ummmm....yes. You can serve in any branch for which you qualify. I know several folks who have jumped between the Air Force, Marines, and Navy.

I served in the USMC 93-03 NAVY 04-08 ARMY 08-14. Retired as SSG.

I don't see much advantage to serving in multiple branches. As you progress in experience and rank there's not much to gain and much to actually lose by jumping branches. Find what you love and make it your own. However IF you do decide to jump branches, do it as early as possible to minimize the impact on your career progression.

I am currently serving in my 3rd branch, Navy, Army, now AF... commissioned in the Army in 1990! I have a friend that stayed Army that is soon to pin on General, I am soon to pin on LtCol. You lose some by switching branches but you also gain a lot of appreciation for service in the military as a whole. Balance your life with the mission of each service but consider serving as a privilege regardless of the branch you serve... cultures are different in each branch. I am often asked which branch I like the best, honestly each one was excellent for that time period of my life. But, consistancy might have served me better...

Two ways to "serve" in other branches;

1-after completing an enlistment in one branch, enlist in a different branch. I served in the Air Force and then the Army and know many vets who've served in more than one branch.

2-Take an assignment to a joint command. Joint commands are staffed by personnel from two or more branches and work together for a common mission.

I'm not aware of any method of cross training between branches because each branch has it's own particular organization and mission.

Yes it is one at a time. I started out in the Navy Seabees in Gulfport Mississippi and ended my career in the Army NationalGuard deployed to Iraq from Hattiesburg Mississippi.
