Kotwica
The kotwica ([kɔtˈfit͡sa]; Polish for 'anchor') was an emblem of the Polish Underground State and Armia Krajowa (AK; tr. 'Home Army') used during World War II. It was created in 1942 by members of the Wawer minor sabotage unit within the AK, as an easily usable emblem for the struggle to regain the country's independence.
