What are the Pros and cons of switching from the Marine Corps to the Army?

Hey! Don't forget about USAF Combat Controllers and Pararescuemen. Those guys get attached to just about every Special Operations in every branch to include NASA. PJ motto "That others may live"

Get away from the Corps. I did the same thing. The Corps is a complete dead end made up of assholes. Army SF is a much better place to be. I went from there to EOD. Best decision. There isn't much life after uniform for SF. There is a lot of opportunities for EOD. Think that over before you commit. And EOD drinks more beer

In 1963 I went to the Army from the Marine Corp. I was a Cpl. when i joined the Army I took a Demotion to PFC. I was in an Ammo Co in the Marine corp and also in the Army. We went on a 30 day field problem, I was the only person who went to the Armorer to get cleaning gear for my M1 carbine. I was made Co. Armorer. When the Supply Clerk got discharged I was made Supply clerk. Then the supply Sgt. went AWOL. I was made acting Supply Sgt. Every time I was moved up to another job I got promoted. I went from PFC. to SP/5 in 15 months. Never worked in my MOs of 2311 (Ammo Tech) I was given a specialist rank. Them we went to vietnam . 205th Ord Plt (Ammo) on 2 weeks notice because the Army didn't have any Ammo Techs in Vietnam in 65. I was still acting Supply Sgt. In March of 66 the Ammo dump at Qui nhon got blown up. about a month later I was offered a battle field comission if I stayed in Vietnam another year. I turned it down because I had been Married only 8 months. Biggest difference i seen was lack of discipline in the Army. And it was always next man up. Before Vietnam it was hard to make rank in the Marine Corp. Some Pfcs had a good conduct ribbon. The younger generation don't care about this. I wanted you to know how it used to be.

It's like you are doing your best to be the best God, has for you. What so good is we have seen others who have done this or the other way. Take this retired marine as one, who now serves in another Army with our Ephesians 6: 10 - 24.

Sigh. It's your life Sergeant, and most of the former Marines I had work for and with me were great and had great success. But, it's all about experience, and in the Corps, you already know the things that you can't learn about life there in books. The Army is the same kind of place, just very different unknown rules and culture. Hell, I've been retired for a while and my Army is as far gone as the brown shoe Army was from me as a young soldier. Think of it this way. It might work, it might not - but if the experience doesn't kill you, there's always a next time. And, most of the time, it doesn't kill you...and when it does, you probably won't know anyway.

Finish your degree and join as an officer. Much better prospects when you separate.

I have a number of Marine buddies who went Army after their Marine enlistment was up, and a few Army buddies who have related their experience with "former Marines" in their ranks, and my impression is that Army command typically appreciates Marines who maintain some of the Marine grease in their military bearing, as they tend to help set a positive example for the rest of the troops. The Marine converts also admit there's not quite as much Army slack as they anticipated, and there are some cultural differences that take some getting used to (both sides, BTW) - "it exercises your tolerance muscles" as one quipped to me.

Pro- on the PT test you only have to run 2 miles, not 3. Con- you are one pound heavier.
Pro- there is no cold salty water. Con- there are plenty of parasites in the warm smelly water.
Pro- no shark. Con- a bunch of alligators, snakes, spiders, scorpions, etc.
Pro- the largest boat is about 10 feet long. Con- the boat is not bulletproof and tends to attract bullets.
Pro- the Army is one head one tail dragon, not a hydra. Con- it's a big heavy dragon.
Pro- our wardrobes change often. Con- unless you are a new recruit, you pay with your clothing allowance.
Pro- we are the many in a big proud family. Con- we are not just the few and the proud.
Pro- movies about us are funny. Con- good luck finding a hard felt drama.

Shall I go on?

I had a platoon sgt. who had come over from the Corps and I had a great deal of respect for him and his service. Each and every day, he wore a clean pressed uniform and helped the rest of us in the unit to have the same. I believe he enjoyed being our Sergeant.

Sometimes it can be the only way to continue your military career... as I approached my EAS in 1985, the Corps was drawing down and weren't offering re-enlistment to thousands of us, (I was injured and processing out as Honorable Medical, but even if healthy re-upping would not have been an option).
The Army has always kept a higher troop strength, and it would be foolish on their part to turn away highly experienced personnel.
