By JOHN VANDIVER | STARS AND STRIPES Published: April 26, 2021 STUTTGART, Germany — A U.S. Army Apache helicopter unit’s planned visit to World War II sites in Poland devolved into a drunken escapade at an off-limits strip club, leading to the suspected drugging of a battalion executive officer who went missing and wasn’t found until the next day, an Army investigation found. The incident involving the 101st Combat Aviation Brigade’s “No Mercy” battalion during its recent deployment to Europe now has multiple officers facing the possible end of their military careers. “The command took immediate and appropriate adverse action against the leaders involved,” Col. Joseph Buccino, spokesman for the 18th Airborne Corps, said in a statement. “Some officers are facing further administrative actions to determine whether they will continue to serve in the Army.”
