A Sterile Field Generator is a type of UNSC technology that is standard and common in Human-constructed medical facilities. The method by which it creates the sterile field is unknown, but it is easily portable and able to be carried in a Field Medical Kit by one person. It is also fairly easy to deploy in active combat.[1]

Because of its portability, the Sterile Field Generator may use a form of radiation that is not to detrimental to humans in order to irradiate the nearby area and eliminate micro-organisms and bacteria that could cause infection.[2]

Although it may be similar to the Regenerator from Halo 3, which is used for a similar purpose, its glow is orange, instead of the green glow emitted by the Regenerator.[3]
