What is it like arriving to your first unit as a Guardsmen?

It's less about when you check in straight out of OSUT/ RSP, and more about what you will be like in 6 months. Initially, you'll be motivated and the new guy. You'll be picked for the usual new guy details/ duties. How will settling back into school/ civilian life balance with your monthly commitment? Will you fall back into old routines or habits, get frustrated being a junior enlisted member of an Infantry Company and what comes along with it. You shouldn't have to say anything, your leadership has been doing this a long time and will be all over it. Good luck!

I can't tell you how this guard was but if you volunteer for everything and are the first one right up front when a Sgt/lt/co etc need something done. Eventually they will see your face over n over while some shit bag never comes fast hoping to not get picked and you'll get sent away n the half ass running guy will be the one stuck outside packing or unpacking connex containers or some other shitty detail. At least that's how the infantry did it.

Apply what you learned at Basic. Be early and in the right uniform. Customs, courtesies, military bearing. Get a watch, notepad, and pen if you haven't already to always have with you. And always remember you were taught how to do everything in Basic ONE way. Your unit will teach you more. Unless you are asked, don't share "In Basic we did this" stories. Everyone went before you. The only new information you would be sharing is how things are done differently. Be quiet and learn.
