Thanks, Gunther. Do you have info about the 498th Forward Support Battalion [A Co. Trans., B Co. Maint., C Co. Medical].

Wow! This is a large request and I am more than willing and capable of detailing this. I will put some stuff together and post here for all to read. I will cover Class I (Food & Water) resupply, Class III (POL Products) resupply, Class IV (Barrier Materials), Class V (Ammunition) resupply, Class VII (Major End Items) replacement/re-issue, Maintenance & evacuation, Casualty Evacuation and Soldier replacement process. Just as a hint, the Brigade Support Area, which is where the Forward Support Battalion lives is where all these Administrative and Logistics activities take place. They handle all of these rear area jobs for the Combat Maneuver elements deployed forward.

The other classes of supply, I won't cover because they are negligible in a combat environment are:
Class II (Personal Clothing Items) - These are the uniforms and field equipment everyone is issued at home station before being deployed to a combat zone. Any replacements are requested through the Unit Supply Sergeant in their company/Battalion field trains.
Class VI (Personal consumption items) - The most notable item in Class VI is alcohol, but also includes toiletries and cigarettes or other consumables. These are ordered by the Supply Sergeant through the S4 Chain of Command.
Class VIII (First Aid supplies) - Requests for first aid supplies goes through the Battalion Medical Platoon Sergeant and the Brigade S4 section.
Class IX (repair parts) - There is a TAMMS clerk (The Army Maintenance Management System) in the maneuver battalion's Maintenance Platoon and in B/498 FSB who order replacement parts through the Division G4.
Self Service Supply Center (SSSC) - Pens, paper and other office supplies are requested through the unit supply sergeants who have access to a SSSC set up somewhere in the rear area.

These classes of supply are not as important as I, III and V. Those three are what keep an army on the move.
