thunder run
n.— «“Looks to me like a ‘Thunder Run,’” I said, recalling reconnaissance-in-force operations of that name I’d seen near the Y Bridge in Vietnam in 1968.…A “Thunder Run” was a unit of armor and mechanized infantry moving at high speed through a built-up area like a city. The purpose was to either catch the enemy off guard or overwhelm him with force.» —by Tommy Franks American Soldier July 1, 2004. (source: Double-Tongued Dictionary)
