Investigators seized a disturbing cache of Nazi paraphernalia, machine guns, grenade launchers and armor during a raid of a quiet suburban home in Washington state.

Charles Ethan Fields, 26, and Levi Austin Frakes, 27, were arrested Tuesday night after an FBI special weapons and tactics team swarmed their residence in Lacey, near the state capital of Olympia.

Officers raided the duo's home in connection to their investigation into a 'violent robbery and theft of military weaponry/armor' at a nearby military base.

Agents seized 35 firearms at the home, including short barrel rifles, handguns, and a MG42 machine gun, a type typically supported with a bipod that was used by German troops during World War II.

They also seized various explosives, body armor, thousands of rounds of ammunition, and other equipment, some of which was restricted Army-issued munitions, according a criminal complaint obtained by the Daily Mail.
