Szare Szeregi
Older Scouts carried out sabotage, armed resistance, and assassinations. The Girl Guides formed auxiliary units working as nurses, liaisons and munition carriers. Younger Scouts were involved in so-called minor sabotage under the auspice of the Wawer organization, which included dropping leaflets or painting the kotwica sign on the walls. During Operation Tempest, and especially during the Warsaw Uprising, the Scouts participated in the fighting, and several "Szare Szeregi" units were some of the most effective in combat. The Gray Ranks also included the White Couriers, who between late fall 1939 and mid-1940 helped smuggle many persons out of Soviet-occupied southeastern Poland into Hungary.
