Wardaddy’s veteran tankers wear the Combat Winter Uniform Jacket, aka “The Tanker Jacket”, as part of their uniform. This would have been the original-issue uniform that tankers at the time would have been provided with. Norman wears the newer M1943 Field Jacket, distinguishable for its many large pockets and greener color. The choice of uniform would have reflected on the status of the men, with veterans wearing the older-issue uniforms while replacements would have the newer issue.
Shia LaBeouf reportedly pulled out his own tooth and did not shower during filming.
The cast underwent a rigorous month-long course of boot camp, in which the final test was manning a real tank during a combat exercise. Despite being considerably older than his cast mates, Brad Pitt made sure that he participated in all of the physical training alongside the other actors.
