Viper

 is a vehicle of the Marines.

Background
It costs 5000 Resources and five Butanium to build this airborne assault vehicle. Any unit with a Construction skill level of three can build a Viper, once research has been completed at an Uplink. Marine ground personnel often cheer when they see Vipers overhead. These choppers are great for troop transportation as well as cover fire. Twin missile launchers raining ordnance from on high can do major damage to any unit or installation. Vipers can transport up to four units over any terrain without restriction.
