In 1958 the patrol boat "RPC Oberst Brecht" was commissioned as a naval squadron of the Army to patrol the Danube in protection of the country's neutrality. The larger vessel "RPB Niederösterreich" was also commissioned 12 years later. The squadron comprised two officers and thirty men. The company which built the vessels closed in 1994. With the fall of Communism and the inability to maintain and repair the vessels, the squadron was disbanded in 2006. Both vessels were donated to the Museum of Military History, Vienna after their decommissioning, and can be toured by museum guests. Austria took first place in the Strong Europe Tank Challenge 2017 as six nations and partner nations battled it out in Grafenwoehr, Germany. The Austrian tankers defeated teams from France, Germany, Poland, Ukraine and from the United States in the exercise. The Austrian soldiers used Leopard 2A4 tanks during the competition.
