Parafoil (Earth-5875)

A parafoil is a triangular parachute glider, made out of strong materials, such as titanium to sustain the weight of fully armored SPARTAN-IIs. Airfoil carapaces are what deploy a parafoil.

Use
SPARTAN-IIs that descend from the low orbit of a planet will use parafoils in the absence of Single Occupant Exoatmospheric Insertion Vehicle. During the training of the MJOLNIR Powered Assault Armor/Mark VI, Maria-062 used a parafoil.
