Vyper
Vypers are essentially a larger variation of the Eldar Jetbikes and are thus more heavily armored and act more akin to a mobile weapons platform. Apparently created by artisans of the Saim-Hann Craftworld, these light skimmers operate in support of other Jetbike Squadrons in order to create a flying Calvary unit of sorts.
Unlike the standard jetbikes, Vypers are piloted by two crew, a gunner and a driver, who share a psychic bond which allows them to better coordinate their actions; it is common for Vyper crews to be blood relatives which would be quite impractical if the Eldar are the only born or if the younger siblings are way too young to even pilot the Eldar's equivalent of a baby truck. Vypers are not heavily armoured, relying on their blistering speed rather than any amount of plating, but mount weapons more commonly found on larger battle tanks: in addition to twin-linked Shuriken Catapults, which can be replaced with a Shuriken Cannon, the rear heavy weapons mount can carry a Shuriken Cannon, Eldar Missile Launcher, Scatter Laser, Starcannon, or Bright Lance.
Vypers are often grouped into squadrons of one to three vehicles, which when well-trained act as one, capable of redeploying in seconds to find the vulnerable spots in enemy armor or escape interceptors attempting to close with it. Like most Eldar wraithcraft, they can also be upgraded with Vectored Engines, Star Engines, Holo-Fields and Spirit Stones.
