The Boulder City Gamble is a military tactic wherein an inferior defending force lures a superior attacking force into a city, town, or large confined space (such as a valley, ravine, riverbed, etc) and then destroys said space with large amounts of explosives. This move effectively sacrifices any defenders left in the area of operation, while also destroying the attacking force and any momentum they’ve gained. This tactic is most famous for its use in the video game “Fallout: New Vegas”, wherein the New California republic destroyed Boulder City during the first battle of Hoover Dam to prevent any further Legion advance.
“The NCR used the Boulder City Gamble to stop Caesar’s Legion from winning the first battle of Hoover Dam.”
