Thermal Blanket

A thermal blanket[1] is a sheet of silver-colored, thermally reflective material that is used to keep people warm, used to help stabilize people in shock and to hide their heat signatures to avoid detection.[2][3]

A thermal blanket was used by the SPARTAN-III's and Kurt-051 to cover Dante-G188's body inside the Sentinel manufacturing facility on Onyx to hide him from the Sentinels of Onyx.[3] It was also used on Dr. Halsey when she arrived on Onyx,[4] and later to create a primitive Faraday cage around Halsey when she was working on her laptop, to avoid detection by the Sentinels' electromagnetic sensors.[1] Thermal blankets were also used to hide armed Lotus anti-tank mines from the Covenant.[2]
