The uniform displayed here is the Gesselschaftsuniform the equivalent of a Mess Dress Uniform in western armies for an Oberstleutnant of the East German Landstreitkräfte. It would be worn at special social occasions such as balls, dinners or other occasions where social dress would be required or authorized. The uniform consists of a light greenish gray colored double breasted tunic with a four button configuration with the straight legged trousers issued to Nationale Volksarmee personnel. Officers of the Landstreitkräfte wore the stone grey trousers with a white stripe down the length of the leg. The uniform would also be worn with a white dress shirt, officer's visor cap and grey standard issue tie along with military issue dress shoes.
Like the General officer's versions, the Gesellschaftsanzug was worn in two configurations: Kleiner Gesellschaft in which only the officer's academy badge and ribbon bars are worn on the jacket or Großer Gesellschaft in which the officer would wear their full medals, shoulder aiguillette and presentation dagger. As with most officer's uniforms in East Germany, each officer's Gesellschaft tunic was often custom tailored for the wearer.
