Side Cap "Pilotka"
Side Cap "Pilotka" was the most common type of cap used by the Red Army during WWII and after until the 1980s. The pilotka was worn during the summer season.
It continues to be worn in modern Russia, although more in the Air Force and the Navy, especially among submarine personnel, where its compactness is inherently practical.
In the Ground Forces the pilotka has been more or less displaced by the kepi and the beret as an undress headgear, although it remains in the regulations. Navy tropical uniform also features the peculiar vizored pilotka, to protect its wearers from the sun. The garrison cap is also the standard dress headgear for women in all of the Russian armed services (except for those units authorised to wear berets, such as airborne troops and marines)
