This paper model is an UD-4L Cheyenne Dropship, a type of combat utility spacecraft primarily used by the United States Colonial Marine Corps, based on the sci-fi horror film series Aliens vs. Predator, the paper model is created by PR Models, and the scale is in 1:250.
The Cheyenne is primarily designed to be dropped from the belly of most USCM spacecraft while they are in orbit and deliver troops and equipment rapidly to a planet's surface. They typically carry the M577 Armored Personnel Carrier, although they can also be used to transport other equipment and even Marines directly in the field.
The UD-4L has the ability to take off and land vertically from unprepared sites, and can also operate as a ship-to-ship transport. Additionally, the Cheyenne has many variable weapons hardpoints and a fixed internal cannon, allowing it to be used in a gunship role in support of ground troops.
