In 2010, Bundeswehr forces equipped with G36 rifles came into a combat encounter with members of the Taliban, in which the barrels overheated, and three German soldiers were killed. This prompted an investigation, which found that two magazines (60 rounds) were enough to overheat the G36's barrel to a severe enough extent to cause accuracy degradation, The G36 is made largely of polymer to keep it lightweight, and it has been suggested that the polymer barrel housing may be the cause of this issue. After the incident, the German Minister of Defence, Ursula von der Leyen, claimed that "The Heckler & Koch G36 has no future in the German army in its current state of construction." Heckler & Koch rejected these claims, asserting that the faults of the rifles came from faulty ammunition, or the tin barrel covering applied by the Bundeswehr, and also cited its widespread usage as proof of the weapon's effectiveness. The Ministry of Defence attempted to sue H&K, saying they were legally obligated to repair their rifles. The court ruled in H&K's favor, saying that since the G36 was designed according to the Ministry's own specifications, H&K was not responsible for any faults in the weapon. The H&K would eventually make their own replacement for the G36 in the early 2000s, the HK416, which was adopted by several countries, including Germany and the United States.
