Disguised as an American serviceman, the Russian soldier Kohler accompanied his superiors, Colonels Antonin Dovchenko and Irina Spalko, to infiltrate Hangar 51 in Nevada in 1957 in search of the Roswell remains.
Biography
Kohler sat with Marelli and other members of Soviet Special Forces aboard a military convoy on their mission to infiltrate Hangar 51 on American soil.
Behind the scenes
Kohler was played by an uncredited performer in Indiana Jones and the Kingdom of the Crystal Skull. While it can't made out in the film itself without the Blu-ray edition, Kohler's name tag and the man who played him can prominently be seen standing next to director Steven Spielberg on the DVD's special features.
