Nelson had served in a United States Marine Corps elite Force Recon unit during World World War II and based the Special Weapons And Tactics concept on the Recon units, believing that a small squad of highly trained police officers armed with special weapons would be more effective in a riotous situation than a massive police response.
Chief Parker liked the proposal and presented it to his command staff He asked for a volunteer to form the Special Weapons And Tactics unit
