グレナダ侵攻
At the conclusion of active combat operations following the Invasion of Grenada, Metcalf and several of his senior aides were caught attempting to bring captured Soviet-made AK-47s back to the US as war souvenirs, in violation of both military regulations and US customs law. Twenty-four AK-47s, along with 24 magazines, were seized by customs agents from the Vice Admiral's plane at Norfolk Naval Air Station, VA when Metcalf and his officers were returning from the Grenada theater.
