The Transportation Security Administration (TSA) got a lot more than it bargained for Monday when checking the luggage of soldier returning home.

TSA officials at Baltimore/Washington International Thurgood Marshall Airport found a missile launcher in the checked luggage of a man from Jacksonville, Texas. According to the traveler, he was an active-duty member of the U.S. military returning home from service in Kuwait and wanted to bring the weapon home as a souvenir.

The item was not live and was safely confiscated by officials. It was taken by the state fire marshal for proper disposal. The traveler was questioned by security and released in time to catch his flight.

"Perhaps he should have picked up a keychain instead!" TSA spokesperson Lisa Farbstein said in a tweet.

The TSA has issued a reminder that military weapons of any kind are not allowed in luggage, either check or carry-on.

There have been many other instances of the TSA discovering surprising weapons.

In April 2018, a traveler had a mortar round in a checked bag at the Evansville Regional Airport in Indiana.

Two novelty bottle openers shaped like hand grenades were found in a woman's check bags in August 2018 at Newark Liberty Airport in New Jersey.
