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

Former Marine, at my first ODA in 7th SFG there were 5 of us former jarheads to include the team leader. Before I joint the Army after leaving the Corp, I visited the AF recruiting office...I was turn away for been a former jarhead. It all worked out in the end. Met many guys with two or more prior service in different branches, so its doable not really practical if you want to advance.

Not simultaneously, but when I was in A-school we had a transfer from the Marines who I want to say was a Staff Sargeant.

Yes I served in USMC,USCG,ARMY NATIONAL GUARD for Alaska and Washington state and did a combat tour in iraq 2004 - 2004. Going into the Marines first eliminating going into any other branches boot camp

ME US ARMY 1978 TO 1982 AND 1982 TO 1992

My son was in Marines for 7 years and transferred to Army last year. He has a lot more opportunities with Army than was available in Marines.

I would say not at the same time; however, joint service may be as close as you get to serving in all of the branches.

I heard back in the late 90's you can go from Air Force to Army but not the other way around....I think after being in the Army that you can't serve any other branch...Just what I heard talking to recruiters

I served in the Marines 92-96 as a 4421 legal pogue. After EAS I activated myself on IRR and lateral moved to 5811 MP. Did a year and change them left the Marines for good.

2005 I signed up for the Navy Seabees as a Steelworker and kept E4 and advanced to E5 before deploying to Kuwait/Iraq in 07.

As a truck driver you'd easily slide to seabees and youd also pick up experience in other construction equipment. Dump dozens scrapers graders excavators etc etc.

It's good to plan but don't neglect the present. When you are a year from EAS then start planning your move.
FYI
I had a blast in the seabees.

Yes Navy 1964 to 1968. Army reserve 1969 to 1993.

Anything is possible if you desire it enough! I originally started in the US Naval Sea Cadets when I turned 14, and then enlisted during Viet Nam as a Data Processing Tech in the Navy. I made it to E-5 and finally switched to the Naval Reserves after the war. I made E-6 and went up a number of times for E-7. However the rate had closed with virtually no promotion potential. I looked for other career options and was accepted into a "Special Warfare" unit on the condition that I would cross-train and swich rates to "Gunners Mate". I worked in the armory for several years, completed the requirements for conversion and made GMG1 (E-6). I was assigned to a PBR "boat" crew and eventually was "Riverine" qualified. When the "Riverine" community was merged into "Naval Special Warfare" I was qualified as a "Combatant Craft Crewmenber". Finally, I started having some health concerns and was told to consider a desk job. Being a member in a "closed loop" Special Warfare Unit, I was allowed to approach other branches of the service to see what they might offer. I was offered a "Ranger Slot" in the Army National Guard in a Battalion that was reclassified as "Air Assault". I accepted the transfer as a Staff Seargent (E-6), was given an ASI="G", and then in my late 40's, successfuly completed "Infantry School". I was assigned to the Recon Platoon as a Squad Leader and after 5 years in the ARNG I finally took retirement. My total span with the military was 36 years. Have Fun!

I'm currently an NCO in the Army National Guard. I've been enlisted, active duty Navy, NCO active duty Air Force, enlisted, Army Reserve, Commissioned Army National Guard, and now... NCO Army National Guard. The military has never been a 'career' for me (even though I started this ride in 1980), it was just a way to give back to our good, old USA.

I believe that you can serve in any of the branches you want as long as you qualify and have completed your prior commitment with an honorable discharge. I am a prior active Marine and retired from the Army after serving over 20 years combined. I have had numerous MOS's in the Army due to having to switch at reenlistment time to get into fields that had the opportunity to get promoted. Been retired now for 27 years after serving 21 years and proud of it. 1st Sgt U. S. Army retired and former active Marine Sgt.

You can serve anywhere. My Lt started as a Marine now he is AF. There was a guy who went to every single branch.

served as combatives instructor and later OSI Agent in USAF from 1959-1970. before switching to US ARMY as a CID agent.....appointed as a WO1 and eventually retired as a CW4

I served in the Army and Air Force, I would say don't change service without a much better reason then you just gave. I joined the Regular Army in 1962 for three years. When I Ets'd I was out for 9 months then joined the California Air National Guard for 6 years. Things were not going well so I quit the Air Guard and Joined the Army Guard for 2 years. Things were not going well there so I joined the \Army Reserves 20 years. I retired in 2005. If you change service you have to remain in your last service for ten years before you can retire. If you change service at 15 years in you have to stay in that service for 10 years until you have 25 years in, if you get caught in a downsize before then you may not be able to retire!

Back in the 70s I knew several SeaBees that went airforce Redhorse . You got a pay grade jump . I was looking at it when the airfarce disbanded it, so scratch that idea

I have a good buddy I served with in the army. After his tour was up in the Army he I listed in the Marines and served for 2 tours in Irac and 1 in Afghanistan so yes you can serve in more than one branch but only one at a time.

Not at the same time, no. lol I have served in the Navy, the Army and the AF, of which I am still in the AFreserve. :) Maybe not on active duty, but in the reserves you can branch jump all you wish. :)

I started out active duty Navy, got out, after a few years went Army reserves, than went ANG, back to the Army reserves, and ended my career in the Air Guard ( 2 OEF/OIF deployments) retired in 2007. Only went to basic with the Navy.

I served two branches, Navy for 9, Coast Guard for 12. Very similar jobs, OS was my rating. Predominantly a sea-going rating. Worked at a MEPS for my last 3 years in the Navy and met quite a few people switching services or prior service entering a different branch. One guy was entering into his third branch of service. You'll find your niche eventually.
