the "kommando landstreitkräfte" also contained some specially trained units - like the 40. fallschirmjägerbataillon willi sänger (later luftsturmregiment 40 willi sänger). the structure and equipment was mostly of soviet design, and the nva operated in close collaboration with the group of soviet forces in germany. there were also reports of a special nva diversionary battalion in south germany equipped with m-48s and m-113s, able to cause confusion amongst nato forces if war came (thus emulating and improving on the example of otto skorzeny's panzerbrigade 150 during the ardennes offensive). however more recent reports throw doubt on the existence of any such unit.
