A direct descendant of the assault/transport hybrid attack helicopters of the 20th century, the large, heavily-armored Hammerhead was designed for long-range assault and infantry support, to act as a longer range complement to the relatively range-limited Orca.
The large central compartment of the Hammerhead can house a squad of infantry, with enough internal maneuverability to allow the unit to fire safely at external threats. For the case of unarmed passengers, the Hammerhead utilizes twin Vulcan cannons to clear the landing space of potential adversaries. Significant additional storage space has been allotted to fuel and ammunition, allowing the Hammerhead to remain in action for days at a time without the need to refuel or rearm.
The high level of customizability of the Hammerhead proved to be an invaluable ally to GDI Commanders on the battlefield, allowing for rapid transport of troops into key combat situations, and beating a hasty retreat when met with overwhelming odds.
A special version of the Hammerhead was seen guarding the GDI Treasury: they possessed wing-mounted sensor searchlights capable of detecting stealth units.

The Russian Mi-24 Hind performs an identical role of a troop transport and an attack helicopter.
Official lore states that the Hammerhead can house a full infantry regiment. A regiment usually consists of more than a thousand soldiers, and even the Mi-26, the largest mass produced helicopter in the world, could only carry 90 troops, so this is most likely a misunderstanding on the developers' part.
