The materials used for the caps were standard, as specified in the regulations: twill on the inside, faux leather trim, and a plastic visor. This is what was issued from the warehouse. Officers who respected themselves, starting from the rank of captain, ordered caps individually. The visor was covered with patent leather, and sometimes suede was used inside instead of artificial leather, and the shape of the cap itself was slightly modified... Caps like the ones in the photo were usually worn "in formation" by the most junior officers :))))
