Beginning next Monday, Oct. 24, Marines won’t be allowed to roll up the sleeves of their uniforms. Marine regulations allow for sleeves to be rolled up on camouflaged uniforms, and doing so is a matter of pride for Marines who feel it makes them look distinctive from the other services.

Marine regulations even have precise instructions for how those sleeves are to be rolled: “The camouflage utility coat will be worn outside the trousers. Sleeves may be rolled up at the option of local commanders. When authorized, utility sleeves will be rolled with the inside out, forming a roll about three inches wide, and terminating at a point about two inches above the elbow. ”
