The left chest logo is the round logo which reads "8th Marine Regiment - Camp Geiger, NC" wrapped around the eagle, globe and anchor. "Geiger Tigers" is arced above it.
The full back logo is the text "Geiger Tigers" and the actual 1/8, 2/8 and 3/8 unit logos. You can get the shirt in either desert tan or olive drab. The logos are black on the left chest and black and orange on the back logo. Semper Fi
