#6 Winning the US title

During his Horsemen tenure, Lex Luger challenged Nikita Koloff for the United States championship.
Koloff had spent most of his career as a faux-Russian heel to cash in on cold war heat, but oddly had turned face after longtime rival Magnum TA was forced to retire after an auto accident. Luger went into the match as the underdog, and a cage was erected to keep the Four Horsemen from interfering.

Unfortunately for Koloff, JJ Dillon tossed a chair into the cage and Luger used it to KO his opponent. Luger raised Koloff in the Torture Rack and the dazed referee ruled the Russian could no longer continue, giving Luger the second most prestigious belt in the NWA.
