Although not seen on-screen, I had these dog tags made to be accurate to the screen-used set that was sold at auction several years ago. In the film, the only evidence that Pitt was even wearing the tags, is from the "veterinarian scene", where the ball-chain necklace is visible. Rank insignia are screen-accurate, compared to frames from the "Basterd recruitment" scene.
Photo #1 is of the pieces in my collection, photos #2, 3, & 4 show the ball-chain necklace, & the relevant rank insignia, as seen on-screen.
