Unlike many other Warthog variants, the Armored Warthog is an upgrade created by the AI Isabel for the crew of the stranded UNSC Spirit of Fire in response to a completely new battlefield problem presented by the Banished and their ruthlessly brutal arsenal, Isabel has assisted the crew of the Spirit of Fire in using available resources to create up-armored variants of the Warthog to deploy and thrive in particularly adverse circumstances.
