To beef up security measures at National Guard recruitment centers, governors in seven states – Florida, Indiana, Arkansas, Oklahoma, Louisiana, Texas, and Wisconsin – ordered their Guardsmen to be armed, reports Fox News.

After the governors' decision to arm Guardsmen, Florida Gov. Rick Scott took it a step further when he signed an executive order to relocate six recruiting centers to armories.

As governor, Scott oversees the Florida National Guard and can act without federal involvement. He also ordered officers to make sure all full-time members of the guard are armed "in the interest of immediately securing Florida National Guardsmen who are being targeted by ISIS."

Authorities say Mohammod Abdulazeez, 24, opened fire at a military recruiting office in Chattanooga, Tenn., on Thursday. Thirty minutes and a police chase later, five military members and the gunman were dead.

While the shootings are being investigated as domestic terrorism, there has been no hard link between the attack and ISIS, authorities said
