Notes: The BO-105 is a small, astonishingly agile, and versatile helicopter. It equips the German Army and has been sold worldwide to countries such as Sweden, Canada, Bahrain, Iraq, Netherlands, Spain, and various South American and African countries. It has an all-weather flight capability, and may carry up to two optional 200-liter internal fuel tanks at the expense of cargo or passengers. No ejection seats are provided, and the helicopter is not capable on in-flight refueling.

The initial version, the BO-105C, entered service in 1968. The BO-105CB is a military light observation/utility helicopter with an uprated engine. The BO-105 CBS is a longer version able to carry more passengers; this is the sort of helicopter that German high-ranking officers tool around in. The BO-105LS is the Canadian version, powered by an Allison engine that is optimized for high altitude and hot weather. The BO-105LS A-3 is the same helicopter, but has more powerful engines. It is known as the "Super Lifter" variant.

The PAH-1 is an attack version, also known as the BO-105P. The PAH-1 has better sighting equipment and more hardpoints; they are sometimes armed with autocannons, and do not usually carry passengers. The PAH-1A1 differs in its engines and lifting capability. The Phase 2 is night attack variant, with a laser designator for use with Hellfire missiles. The BSH is a helicopter escort; it normally is armed with Stinger missiles, and carries sensors that allow it to detect and attack enemy helicopters and aircraft.

Twilight 2000 Notes: Delays in the Tiger attack helicopter meant that the PAH-1 had to see considerable service as an attack helicopter in the Twilight War. The BSH was never built.
