An additional area within the Polish command structure was formed by the units of the Directorate of Sabotage and Diversion or Kedyw, an elite formation that was to guard the headquarters and was to be used as an "armed ambulance", thrown into the battle in the most endangered areas. These units secured parts of Śródmieście and Wola; along with the units of Area I, they were the most successful during the first few hours.
