# Order of Battle

> Order of Battle is a free unofficial army builder for Age of Sigmar 4th edition and Warhammer: The Old World. AoS lists are built by regiment — matched play or Path to Glory — then Play tracks wounds and phases. The Old World builder (beta) writes Grand Army lists with composition caps. You don't sign up; the lists live on the device.

## About

Order of Battle is a browser hobby helper for Warhammer Age of Sigmar (4th edition) and Warhammer: The Old World. Free fan project: no ads, no subscriptions, no Games Workshop affiliation. AoS catalogues come from the community BSData Age of Sigmar 4th edition project. The Old World catalogues come from community The Old World data. Order of Battle doesn't write or maintain that data and isn't responsible for it, and lists stay on the user's device. Every image on the site is fan-made, not official Games Workshop artwork. Rules summaries are written in our own words. Points and rules in the app are helpers only. Always check the official Games Workshop publications.
