WASHINGTON (AP) — Defense Secretary Pete Hegseth said Thursday that he will allow service members to carry personal weapons onto military installations, citing the Second Amendment and recent shootings at bases across the country.

In a video posted to X, Hegseth said he is signing a memo that will direct base commanders to allow requests for troops to carry privately owned firearms “with the presumption that it is necessary for personal protection.”

He said any denial of a service member’s request must be explained in detail and in writing.

“Effectively, our bases across the country were gun-free zones,” Hegseth said. “Unless you’re training or unless you are a military policeman, you couldn’t carry, you couldn’t bring your own firearm for your own personal protection onto post.”

Questions about why service members lacked access to weapons have often emerged following shootings on the nation’s military bases. Such shootings have ranged from isolated events between service members to mass casualty events, such as the shootings by an Army psychiatrist at Texas’ Ford Hood in 2009 that left 13 people dead.
