NORFOLK, Va. (AP) — Officials say Navy sailors will suit up in battle gear and take up fighting positions at U.S. bases during the nation’s largest anti-terrorism exercise, an effort meant to gauge their response to multiple attacks.

Navy installations in the continental U.S., Guam and Hawaii will participate in Exercise Solid Curtain-Citadel Shield from Tuesday through Friday. The training will give military leaders a snapshot of readiness as the 10th anniversary of the Sept. 11 attacks approaches.

The Navy plans to simulate real-world threats, incorporating lessons learned from the 2000 bombing of the Navy destroyer USS Cole and the 2009 Fort Hood shooting, among others. It all will be monitored from a control room at Naval Station Norfolk, the world’s largest naval base.
