The U.S. military has outlined security upgrades for recruiting stations, reserve centers and other facilities after Thursday's fatal shootings in Chattanooga a military spokesman says.
Adm. William Gortney directed additional "force protection measures" in orders sent Sunday night, according to Capt. Scott Miller, a spokesman for the U.S. Northern Command, which covers military bases in North America.
"The expanded measures are to increase vigilance and sustain security of military personnel and facilities," Miller says. He would not go into further detail Monday to "protect operational security."
The shooting prompted governors in at least a half-dozen states to authorize National Guardsmen to take up arms to protect recruiting offices and installations.
