[header] How to fold army combat uniforms [title] Lay your jacket on a flat surface. [step] A clean floor or table top usually works well for folding a uniform. Lay your jacket as flat as possible and run your hands over it to remove any wrinkles or creases. <sep> (A) [substeps] Some army uniforms have an extra paper sleeve that holds the uniform together when you fold it. Trying to fold the same sleeve a second time will seem old-fashioned, and potentially awkward. (B) Place the jacket so that the edges are even-one side against the table and the other side against the floor. [substeps] Make sure that the corners are facing outward. (C) [title] Zip up your jacket and seal the velcro. [step] If your jacket is not already zipped and sealed, do so before folding it. (D) [substeps] Don't worry about smoothing the fabric. Just fold it so that the parts of the jacket are exactly the same size.
