Matthäus Hetzenauer was an Austrian sniper in the 3rd Mountain Division on the Eastern Front of World War II, who was credited with 345 kills. His longest confirmed kill was reported at 1,100 meters (3,600 ft).

Hetzenauer was also a recipient of the Knight’s Cross of the Iron Cross. The Knight’s Cross of the Iron Cross was awarded to recognize extreme battlefield bravery or successful military leadership.

He utilized both a Karabiner 98k sniper variant with 6x telescopic sight and a Gewehr 43 with ZF4 4x telescopic sight. He saw action against Soviet forces in the Carpathians, Hungary, and Slovakia. On 6 November 1944, he suffered head trauma from artillery fire, and was awarded the Verwundeten-Abzeichen three days later.

Gefreiter Hetzenauer received the Knight’s Cross of the Iron Cross on 17 April 1945. Generalleutnant and Divisions commander Paul Klatt had recommended Hetzenauer because of his numerous sniper kills, which totaled two enemy companies, without fear for his own safety under artillery fire and enemy attacks.

Hetzenauer was captured by Soviet troops the following month and served 5 years in routinely appalling conditions in a Soviet prison camp. He died on 3 October 2004 after several years of deteriorating health.
