The U.S. Army Field Artillery Museum is one of Fort Sills key military-history stops. Its exhibits move from early cannon and horse-drawn artillery through modern fire-support systems, using weapons, uniforms, vehicles, and training material to explain the branchs development.
It is most useful if you are already visiting Fort Sill or the Lawton military-history circuit. Bring identification and check access rules before setting out, since the museum is tied to an active Army post.
