According to the order of the People's Commissariat of Defense of the USSR №187 of July 5, 1940 in the Red Army and militia were introduced earflaps. Prior to that, the Red Army men wore the legendary Budenovka helmet. The Soviet-Finnish war showed their absolute unsuitability in the winter cold. Upon learning that the Red Army men were freezing in the Karelian forests, Leningrad companies urgently began to provide soldiers with earflaps - they got to the units with the wording "for experimental tests".
During the war the Red Army received more than 24 million hats. Without any special transformations, not counting changes in the size of fur cap parts, the hat with earflaps remained in military service until 2010.
