The t-shirt worn by the Navy SEAL Team Six member who shot and killed Osama bin Laden is going on display at the 9/11 Memorial Museum in New York City, USA Today reports.

“It’s a shirt that symbolizes the effort of the entire SEAL Team Six,” Congresswoman Carolyn Maloney (NY-12) told the New York Daily News on Wednesday. “It’s a symbol of the success of that high-profile mission dubbed ‘Operation Neptune Spear’ that ended the global manhunt that started even before 9/11.”

According to the New York Post, due to safety concerns, the identify of the special forces operative who shot and killed bin Laden has never been revealed. The New York Post notes that the shirt is brown with a black American flag on the sleeve.

President Barack Obama announced bin Laden’s death on May 1, 2011. Social media exploded as news of the terrorist’s death began to spread. The event set a then-Twitter record, according to CNN, of 3,400 messages per second.
