The U.S. military is asking recruiting centers to increase security following last week’s shooting in Chattanooga, Tenn., that claimed the lives of five service members.

On Sunday night Adm. Bill Gortney, who heads U.S. Northern Command, directed hundreds of centers across the country to take small steps such as enhancing surveillance and closing the blinds at offices, the Wall Street Journal reports. The Department of Defense is currently considering more significant steps to protect recruitment offices, reserve centers and ROTC facilities from possible future attacks.

U.S. Northern Command spokesperson Capt. Scott Miller declined to comment to the Journal on the details of Gortney’s directive but said they are designed to “increase vigilance and safeguarding of personnel.”

On Thursday Mohammod Youssuf Abdulazeez, 24, opened fire on a strip mall recruiting center before driving to a Navy office where his shooting rampage continued. Officials have not confirmed a motive but are investigating the attack as an act of domestic terrorism.
