The fact you’re asking here and now already puts you ahead of your peers. To caveat off a couple of things @logisticus mentioned.

Standout by knowing and doing your job – doing it to standard, efficiently, and effectively. If you don’t know, ask. If you want to know a better way to do something, look for it. The NG is full of young officers who only come in on the weekend and expect to be spoon fed what to do, when, etc. Prepare yourself and expect to work long hours between drills with no compensation other than well executed training.

First thing is you should know and understand what your rater/SR expect out of you. What are their goals? What are their expectations? A copy of their support form would be nice, but ask for a counseling, and take note. Note when they freak out about something or make a show that something is/was important to them. As your peers, the 1SG, and others who have been around for a minute about pet-peeves, how your rater operates, etc.

Planning is huge, especially in the NG. Every training event is a mission, and well planned training is why Soldiers joined the ARNG; so plan accordingly. From what resources you will need, through execution, to desired end state. Be able to speak it out, what’s more, be able to translate your plan to paper so others can follow your intent. I tend to stick with the tried and true OPORD format when I plan things, just so I know I got everything. Situation – why are we doing this; what are the references we’re using (T&EOs, etc.). Mission – pretty self explanatory. Execution – training objectives/goals (end state); concept of the training/overall walk through; scheme of maneuver (more specific step by step of what you see as how the training should go); timeline; uniform; etc. Support – what resources will you need; how they will be delivered; medical on hand. Command – Who’s in charge; what are the signals used… And so on. Even something as simple as an APFT should be planned well; Soldiers see when something is half-a**ed and thrown together, and their attitudes and morale reflect accordingly.
