The left chest logo is the logo with the pagoda and the snake with the text "The Rock - Camp Schwab - Okinawa, Japan" wrapped around it. The full back logo is the picture of Camp Schwab with the text "Camp Schwab - Henoko, Okinawa" wrapped around it. For those buying the shirt for someone who is or was stationed there - Henoko is the name of the town in Okinawa where Camp Schwab is located.
You can get the shirt in either black or olive drab. The logos are white and black on both the black and olive drab shirts.
