The long strange trip
The Imperial Marines are the armed fighting forces carried aboard starships. Marines deal with piracy and boarding actions in space, defend the starports and bases belonging to the navy, and supplement other ground forces such as the army.
By reputation, the Imperial Marines are sent in when something or someone presents a serious threat to the well-being of the Imperium and its member worlds. They are never used lightly, and once committed, they never leave a job half done.
The Imperial Marines were founded by Cleon Zhunastu, who transformed the landing forces of the Sylean Navy into the Imperial Marines over 1,100 years ago. Weapons and tactics have changed, but the Marines’ basic function remains the same; move fast, strike hard, and enforce the Emperor’s will.
