==Behind the scenes==
*The original beret model resembles actor WikipediaClint Eastwood|Clint Eastwood.
*Originally, the HECU was to feature a special type of soldier nicknamed the Human Sergeant. The character was cut, but his head model was used a generic HECU Marine in the final game.
*The drill instructor player model used in ''Half-Life Opposing Force'' was modeled after the character Gunnery Sergeant Hartman (played by WikipediaR. Lee Ermey|R. Lee Ermey) from the movie ''WikipediaFull Metal Jacket|Full Metal Jacket''.
*''Half-Life''{{'}}s Marine models were used as placeholders in the early screenshots of ''Opposing Force''.
