Do they sell uniforms here?

Yes, as of MAR2022, they sell Army, Marine and Navy uniforms. Depending on what exactly your looking for (pants. jacket, PT uniforms, ribbons/awards/insignia, boots, hats). That is some of the military clothing items for EACH branch, that I have seen there. Note though, each item, I mentioned above, there are select sizes. Sometimes they have the size I need and sometimes not.

Navy & Marines only -- but it's limited stock. Suggest buying online & sending it to the NEX or traveling up to Jax. No Army. No Air Force/Space Force. No Coast Guard.

Yes for Navy and Marines
