“It is considered a cyber threat,” Lt. Col. Robin Ochoa, a spokeswoman for the Army, told Military.com. “We do not allow it on government phones.”

In an email to NBC News, Lt. Col. Crystal X. Boring, a public affairs officer for the Army, said the Army was following the guidance of the Office of the Secretary of Defense that TikTok is a potential security risk.

“The message directs appropriate action for employees to take in order to safeguard their personal information. The guidance is to be wary of applications you download, monitor your phones for unusual and unsolicited texts etc. and delete them immediately and uninstall TikTok to circumvent any exposure of personal information,” Boring said.
