The United States Marine Corps

What about the United States Marine Corps? Mind you, most Americans are fixated on the sins of Nazi Germany, and Commie Russia to a lesser extent.  Still, we all know that the US Marine Corps is every bit as lethal and vicious, about coming up with ways to torture their victims to death, than either the Nazi SS or the Commie NKVD.  This was, of course, especially true in South East Asia, during the Conflict in Indo-China.
