The U.S. Navy has sent an apparent warning to China that it better stop harassing American troops with lasers. The message came after a Chinese military destroyer aimed a laser at a Navy-operated P8-A Poseidon surveillance plane.

“You don’t want to play laser tag with us,” the Navy posted on its official Instagram account on Feb. 28.

The incident happened on Feb. 17 in international airspace over the Pacific Ocean about 400 miles west of Guam, a U.S. territory, according to the military.

“The laser, which was not visible to the naked eye, was captured by a sensor on board the P-8A. Weapons-grade lasers could potentially cause serious harm to aircrew and mariners, as well as ship and aircraft systems,” the Navy said in a Feb. 28 release, calling the incident “unsafe and unprofessional” on the part of the Chinese.
