DAYTON, Ohio — A new traveling interactive exhibit at the National Museum of the United States Air Force gives patrons and military history lovers a chance to experience an aspect of military operations rarely mentioned in history books: defecation in austere locations.

“When people normally visit a museum, they usually come to see cool weapons and aircraft and to learn about significant events in American military history,” said Leona Billings, a senior exhibit project manager who, as a retired chief master sergeant, has plenty of first-hand combat deployment experience. “But there’s more to war than fighting. You gotta poop. And most people don’t realize the logistics involved in tactical crapping.”
