Thermoenergetic Screen
this form of heat protection was developed by the Old Republic during the height of the Clone Wars. Using a thermoenergetic screen, a clone trooper could be encapsulated in a small pod, which could be ejected from a transport ship so that the trooper could reach a drop point on a planet's surface. This eliminated the need for large, expensive dropships that provided enemies with a large target. The small, expendable pods were hard to detect, allowing a trooper to reach the surface swiftly and undetected. The thermoenergetic screen deflected the incredible heat that was built up upon entry into a planet's atmosphere, keeping the trooper inside safe.
