Harvey was a Miltiaman from the post-apocalyptic settlement of Pop-Up.
In January 1954, Pop-Up was visited by six New American Republic (N.A.R.) Regulators who wanted the community to be part of the ever growing American Empire which was ruled by Judge George Ramsey. The Pop-Up settlers were upset by the way the 'invitation' sounded like an order and declined when Harvey shot the N.A.R's messenger and his fellow Pop-Up citizens killed four of the remaining five regulators. A few days later on the 10th, neighbouring community Haven and remnants of the United States Army under the command of Captain Marvin Kawecki visited. The spokesman for Pop-Up realised that the Judge would probably retaliate agreed to join an alliance with Haven and the U.S. Army to destroy the Republic.
Pop-Up settlers did fight in the First Battle for Tunnel-Through which turned out to be a failure with an unknown amount of Pop-Up casualties.
