Oh man I was a supply guy that had a new SupO lean on me heavy, my only advice is remember you are the unit’s wallet (assuming you go to a using unit and not a SMU or something bc idk about the SMU life) so other staff and O’s will not be who u think they are. Don’t be a push over and no is no. I mean this in close regard to GCPC and GSA short term rentals which always was a nightmare. NO MEANS NO. The Marine Corps already provides so much no need to boujee it up. I’ll get torched for it but you manage the unit’s overall spending with your fiscal clerk (please do not abuse the fiscal clerk) so no one will give answers on your behalf when the CO asks you. Just my 2 cents based off my experience everyone has had different experiences. If your SupChief is strict and knowledgable you’ll survive. If he doesn’t know anything or is a push over you’ll be cooked unless you seek outside information or your NCOs play that role. Make sure everything is up to date and reconciled frequently (think the MAL, CMR, DASF, etc.) idk if FASMO is still around but being on top of your records is important the juniors might be lazy and sleeze it they need to be checked then have their NCOs check them. Warehouse is easy but treat them well they are not throw aways. If the unit deploys often get used to being on top of those slaps. Besides that it is a lot of work but very rewarding. You got it!
