Ask a sustainment staff where fuel stands and someone pulls a report. Ask about munitions and a different officer opens a different spreadsheet. Ask about repair parts and the answer comes from a system of record that was current yesterday afternoon. Each answer is right on its own terms. Put them next to each other and they rarely describe the same day.
Classes I through IX
The Department of War sorts supplies into ten classes. Classes I through IX cover everything a force consumes: subsistence (Class I), clothing and individual equipment (II), petroleum, oils and lubricants (III), construction materials (IV), ammunition (V), personal demand items (VI), major end items (VII), medical materiel (VIII), and repair parts (IX). Class X is material for nonmilitary programs such as agriculture and economic development. Each of Classes I through IX has its own planning factors, its own reporting rhythm, its own system of record, and often its own staff officer.
That division makes sense for managing supply. It makes less sense for deciding. A commander does not ask how Class III is doing. A commander asks whether the lead element can keep moving for three more days, and the honest answer depends on fuel, ammunition, parts, and medical materiel at once.
What one picture means
- Days of supply for every unit, every class, at any time step, on one screen.
- The age of each unit's last report shown beside its numbers, so a stale figure cannot pass as a current one.
- Scheduled resupply included in the projection, so the picture shows what the plan delivers, not just what is on hand.
- The same numbers feeding the alerts, the what-if comparison, and the commander's one-page brief, so nobody reconciles three versions before a meeting.
Built as a core plus modules
ALLCLASS is a bolt-on platform. It sits beside the systems of record a force already runs and reads from them; it replaces nothing. The core holds the picture, the forecast engine, the alerting, and the brief. Modules add depth by class of supply and by function. Today the fuel, munitions, repair parts, and medical materiel modules are modeled in depth, along with distribution. The remaining classes are on the roadmap and are stated as such on every screen.
That structure is deliberate. A force buys the classes it fights with first. A wargaming center buys the planning module. A distribution directorate buys routing. The picture is the same for all of them.
Where the numbers come from
Every figure in the picture opens a card showing its formula, its inputs, where each input came from, and what the calculation does not model. The planning factors behind the forecast carry citations to the manual, page, and table, or an attribution to the subject-matter expert who supplied them. A staff officer who hands a commander a number is accountable for it, and the software is built so the officer can defend it.
