Welcome to my store.  I started collecting military insignia when I was about seven.  In all those years, I always wanted to find a a single reference book on U.S. military rank insignia.  A single source that I could go to for the answers withourt having to pull five or six different books off the shelf.  I never found it, so I wrote it.  These books cover the insignia as they are/were worn on service and dress uniforms.  I hope you enjoy them and find them useful.
