What should I expect as I transition from the Marines to Army Cav Scouts? What are some do's and don'ts?

If you have combat experience, don't wear your Marine patch on an Army uniform. It is, by regulation not allowed. Many who come over assume a combat patch is a combat patch it is only authorized for Army patches and soldiers who were attached to Marines in Certain circumstances. Learn your equipment, some of it may be new to you, get a -10 manual (operators level, commonly referred to as a "dash 10") and learn about it, how to troubleshoot it when it goes down. If you are in a Bradley they are good pieces of equipment when taken care of. The Army and USMC have two different missions, try not to dwell too much in the USMC past, it gets annoying to those around you.

I served with a number of former Marines in the guard and we busted their b**** but it was all in fun! We served in Iraq with many of them and they are our brothers no matter what branch they were in!

The Cavalry is a proud organization with a lot of history. Don't knock the Stetson or spurs and definitely don't make comparisons to the Infantry.

Your professionalism will be an asset coming over.

You will have to learn a few terms and a slight difference in rank. For example the Marines I know call their Staff Sergeants their full rank Staff Sergeant. That's not wrong in the Army but you usually only call an Staff Sergeant a Sergeant in general conversation.

The same applies to Sergeant First Class and technically Master Sergeant, however many Soldiers typically call a Master Sergeant by their full rank as a show of respect for the rank.

A First Sergeant will be called First Sergeant and a Sergeant Major and Command Sergeant Major will be called Sergeant Major though I imagine you already knew that.

You may be allowed to wear your awards and certain devices on your Army Service Uniform (ASU) from the Marines. I would check to be sure but the Army is a bit more accepting about the awards of other branches. While I was in Basic we had 3 Sailors switching over and they were all allowed to wear their former Navy ribbons and badges.

Hey I'm the saw gunner in the picture

I transferred from the Marines to become an Army Officer. I would not say the transition was smooth. There is a huge difference in mindset. Going infantry to scout is less of a leap than infantry to Military Police. Traditions are of course different. Army doesn't place such almost Godlike status in the NCOs. Officers are much more involved in training. But given the chance to go to war with Army or Marines, I go to war with the Army.

Depends on what your job in the Marines was and what your attitude toward the Army is.

My buddy transferred from a Marine Tank Scout to a Cav Scout. He said in some ways it was harder but for the most part it was about the same. Marines send their Plt Sommandars to the Army Scout School anyways (or at least they used to) so it wasn't that much of a difference. From what he said, the Cav Scouts were good to go. And in my experience you take Army units individually...some are locked on and some are bags of ass.

The Marine Corps was instrumental in my success in the Army Guard. The drive and determination we were taught helped insure my success. It helped me overcome some serious obstacles. I got knocked down a couple of times, but I got back up and moved on to better things.

You're gonna be totally floored at how fucking lax it is. It's pretty much a free for all in the U.S. Army anymore. Just be sure to not act like a Marine anymore. Act like a 2 year old child that doesn't get his way and you will fit right in. If you do that then you will get promoted, thrown in the stockade for a couple months and then come out a millionaire because of all the book and movie deals. Easy as pie.
