BO 105 PAH-1 (Panzerabwehrhubschrauber: "anti-tank helicopter") was an attack version of the BO 105M multi-purpose helicopter, developed by MBB. In this configuration, the helicopter was able to carry up to six HOT missiles. Between 1979 and 1984, a total of 212 BO 105 PAH-1 helicopters were delivered to the West German Army. However, the helicopter's inability to perform combat missions at night, as well as its low survivability and self-defence capabilities, eventually led to its replacement by the Eurocopter Tiger. The last BO 105 helicopters were retired from service by the German army in 2016.

Introduced in Update 1.83 "Masters of the Sea", the BO 105 PAH-1 is a light, fast, manoeuvrable, and small helicopter capable of delivering quick and swift attacks as well as quickly withdrawing from ground fire. However, for its lightness, it has to pay with the absence of any armour. Although small, its arsenal includes 12.7 mm machine guns and a set of HOT anti-tank guided missiles, and for protection against heat-seeking missiles, it can be equipped with flares.
