This sound is from Davian Thule - Dawn of War Soundboard

Captain Davian Thule (Also known as Davian Cool) was a captain of the Blood Ravens 4th company. He appeared in Dawn of War Dark Crusade and throughout the entire Dawn of War II franchise, where he sorta lost his accented voice, sounding a bit gruff, and got interred into a Dreadnought afterwards (which is probably the best thing that could happen to him).
