The Boeing CH-46 Sea Knight was a medium-lift tandem rotor cargo helicopter, used by both the Global Defense Initiative (GDI) and the Brotherhood of Nod in the First Tiberium War to provide all-weather, day-or-night front-line transport of combat personnel, supplies and equipment. Assault support was its primary function, and the movement of supplies and equipment was secondary.
[edit] Background
The helicopter could carry a fully equipped squad of infantry, and deploy it anywhere on the battlefield with the use of retractable rappelling cables, mounted at the rear exit. For close range defense, certain versions were equipped with two miniguns mounted on each side to repel potential enemies from the landing site. However, its light armour made it extremely vulnerable to anti-aircraft fire, especially while unloading troops or while hovering. Mobile artillery units were found to be particularly potent anti-air weapons, and were regularly used against these helicopters. The helicopter stood a better chance while moving. Certain specialized helicopters could also carry a single battle-ready vehicle underneath them using cables and deploy it in the field.
