German helmet with a white and red band of the Warsaw Uprising insurgents of 1944

A German helmet with a white and red identification band of the Warsaw insurgents in 1944, bearing the sign of the Grom military unit (G letter with a thunderbolt, Polish: grom = thunderbolt). The sign is an identification symbol of the first paratrooper unit established in 1942 as part of the Polish Home Army. It was designed by the graphic artist Marian Walentynowicz. The Home Army Paratroopers, known as “Cichociemni” (silent and unseen), carried out the airdrops of weapon, money, etc., from the territory of Great Britain to Poland. The Cichociemni paratroopers were a group of 316 individuals, including one woman, Gen. Elżbieta Zawadzka, who underwent special training.
The helmet, a Stahlhelm, is a popular type of military headgear whose name comes from German (Stahlhelm means “a steel helmet”). The Stahlhelm was introduced in the German army in 1916.
