First Initial Counseling

I Totally disagree 2LT Sorge, you don't need his prior NCOERs. Evaluate him for the job he is/will be doing. It's against regulations to ask for prior evaluations. Lends to promoting a bias opinion on your part - good or bad.

Yes, you and he are a team - fact! But, you are the Platoon Leader and he should have some expectations from you laid out before him. What are your goals for the platoon? Are you in the position first or are you replacing another officer? Goes to experience.

Find out his goals for the platoon and see where possibly you can leverage his experience as well as the Squad Leaders to work towards those goals.

You also need to understand what your Commanders goals are for the Company and tie those into your counseling so you are "nested" with higher.

Just my thoughts .....

Does he support you 1LT Ryan Millican?
I would discuss with him
(1) how you both can improve the leadership skills of the squad leaders.
(2) how you can use down time to improve the platoon's training, esprit and teamwork.
(3) get his advice on what you could do to improve one or two weak areas of your own - if you trust him implicitly.

tell him your new and your here to learn from him, don't expect to come in the first day and have a grand plan. He will take care of you if you are open and honest with him.

Some good advice here. You and the PSG are a leadership team. Make sure you convey the PSG is in charge of NCO stuff and you stay out of it. You both need to know who the problem children are, if any, and make sure a corrective plan is in place. BTW that plan should be what the Skipper and SEL support and how they want things done. Discuss where the troops are in terms of skill, development, distractions, etc. You have to know where your platoon sits among the other elements of the Command so you know when to step forward for them and when to keep your mouth shut. Make sure you both use the CoC on the E and O side correctly.

Since your PSG isn't a newbie, find out what his/her plans are for their own development. The PSG should want something out of the tour. So you'd make sure excellent performance is highlighted up line. Make sure neither of you are punching tickets. There's people counting on you. Don't let them down. There should be 2-3 biggies you both want to make happen over the next year. Identify them and agree on the game plan to make it happen. If either of you makes a 100 item shopping list, come out my way. I have this plank you need to walk.

For sure include that you expect him to help develop you. You are his mentee and he/she your mentor. That relationship must be established ASAP. Good luck.

LT,
I'd offer this as food for thought. Take the approach of a Servant Leader. You won't or shouldn't have to establish your seniority or higher rank...PSG has been in the Army and understands the rank structure. As far as laying out your expectations of him, I would expect that he will keep you informed of anything issues that arise within the platoon (further clarify that you will support him in how the enlisted matters are handled but that you trust him to keep you in the loop). Next I would expect to have clear and open lines of communication (share how you prefer to receive your communication and ask what his preferences are as well...that way you guys can effectively approach one another). Your goal should be to learn from him and you should express your desire to be involved with the platoon yet you respect his time with them as well (set boundaries so that you don't appear to be micro-managing).

Ensure that there are safety checks in place that prevent you from having both the compass and the map at the same time....trust me, he'll probably laugh; if you actually put that in the counseling, you'll be the most memorable PL that he's had and he'll probably frame it.

Hell, come up with some subtle signals that the two of you guys can agree to so that neither of you have to make the other look bad in front of the soldiers. That way he can respectfully and quickly communicate "Sir get the hell out of here, we're in the middle of something." or "PSG, this is urgent and I need to speak to you privately." That way you both appear to all that you're working with great chemistry and nobody has to go alpha dog on the other. It's mutual respect. Have the expectation that he gently remind you of your faults, aid in the reformation of said faults and defend your character; ensure that you will do the same.

Positive reinforcement goes along way; you focus on making him look like a rockstar along with the members of the platoon and they'll fall on their swords for your success.

My two cents, for what it's worth. I had a marketing degree and my own business before I enlisted in the Corps. I just did it for the challenge haha. So now I'm a 29 year old E-4 who's the same age as my E-7.

He's not going to be able to tell me much about life, since the Corps all he knows, but he knows way more about the Marines. I respect him because we understand each other in that aspect.

I had a negative counseling for having a smoke grenade in my bag. My reason was nobody told me to turn in back and i remember asking and didn't get any answer telling to do so. Is that one bad for my carrier?

I would use this as a starting point
