What will infantry school be like as a prior service SGT from the marines that already has a combat deployment under their belt goin army ?

Elvis was drafted.

Best to keep your “when I was in the marines we did it this way” comments to yourself.

When I first got to basic at Benning, had one guy in our 30th AG barracks. He made sure to tell everyone, and I quote, "I'm former Marine." He reminded us all of it, constantly. I was brand new to the military, so, I didn't quite know what to think but over the course of the 4 years I spent as Active Duty Army, I realized that that guy was an absolute tool and that there must have been something negative from his time in the Marine Corp because I have never met a Marine in the civilian world who called themselves a, 'former Marine.'

I attended OCS Officer's Candidate Scholl after having served 1o years as an EM enlisted man. It didn't take long for a couple of other prior enlisted to speak up out of turn, correcting and EM instructor. The TAC officer immediately called them out of ranks and sent them packing never more to be seen. I remember complaining to my room mate about how tough it was going to be, looking for sympathy. He quickly set me straight, saying yes OCS was going to be tough, but not to make it any worse by complaining to him. I quickly apologized to my room mate and said I was wrong and wouldn't repeat my error. We both graduated as 2lt and were soon off to Vietnam and I never saw him again, I sure hope he fared well. I ended up serving a second tour later on as a Captain Infantry Cmdr. PS I earned a serious purple heart during both tours. I am retired with twenty years and will be 84 years old Feb 21, 2022. PS one of my classmates Vladimir Sobichevsky a Russian born soldier attended my class, and he retired as a Full Colonel and died July 2016. He was a great candidate and and great officer. Last I saw of him was as he was entering Costco in Sand City and stopped to say hello. He was a soldiers Soldier, I think he attended just about every school the Army Offered, including green Beret Special Forces. Det. A.

Semper Fi, they will be jealous!

Now that we're 10 months past the original posting, and a solid 5 months after your original Marine ETS date, I'm curious what REALLY happened Sgt (Join to see) Did you end up on day 0? Reclass school? What rank did you bring over?

I hate stories with no closure!

As a Senior Drill Instructor I used my prior service Soldiers to my advantage. I placed them in leadership positions in my platoons and left them there the entire cycle. It helped build you up for your next assignment but also placed you in a position of greater influence to the less experienced trainees. I say all that to say this…not all Drill instructors think the same way. Don’t be surprised if you are placed in the back row and told to keep quiet. Just be ready to be an asset to your new team and learn the differences in service. Welcome back to the force.

Have faith that your leadership insights will guide you meritoriously. Consider this approach. When observing leadership you agree with based on your vast and important experience, perhaps join in the process by speaking up making a comment in the form of a question. As long as you believe in your comments and aren’t making them for purposes of self-promotion, but making them instead because you believe in them and your input is expected as a team member or one being put in harms way, you should do fine. Humility eventually stands out, not as weakness, but as respect for everyone else and a form of true leadership. Let everyone else take credit, as long as the mission is carried out successfully. When there is mission failure, own it. Of course strive always to choose words very carefully and speak truth. Never loose sight of the big picture of the war being fought whether the mission is successful or a seeming failure. If you don’t believe in the war you are fighting, move on and get out and redirect the arrow of your life’s path. That is your higher purpose. Do you realize you are in a war right now? As you are promoted up through the ranks, you will be tasked to face demons that test your ethics and morals as never before. The services need personnel who are prepared to face these tasks with inner strength that does not crumble like a house of cards. Only truth seekers need apply.

When i went through OSUT, we had prior service who were given a lot of leeway. They didnt participate in the shark attack, they were bunked in a separate room away from the bay with fresh recruits, were allowed to have their phones, and when we weren't formed up, marching, or doing training, they didn't have to participate(random smokings, random BS, shit like that). They were also placed in leadership positions (Platoon guide, squad leader, ETC). Our DS leaned on them a lot to help us learn shit that they already knew.
