Heeresgruppe Weichsel
The German reorganisation of command structure that resulted in the creation of Army Group Vistula was accompanied by the release of a few extra formations for the defense; the V SS Mountain Corps, with two reserve infantry divisions, was deployed along the Obra and the prewar border fortifications known as the "Tierschtigel Riegel", while the "Panzergrenadier-Division Kurmark" was ordered to reinforce it.
