Factual error: U.S. marine utility uniforms have the Marine Corp Emblem and USMC printed in black ink on the left shirt pocket. Private Duke Slater's uniform does not have it printed on his left pocket.
Other mistake: Private Duke Slater's utility uniform shirt is different from the other Marines. Duke's uniform has square pocket flaps with the button exposed, an exposed button front shirt and the sleeves do not have button cuffs. The other Marines' uniforms have tapered pocket flaps with a hidden button, a hidden button front shirt and the sleeves have button cuffs.
