Fort Hood will hold its annual Force Protection Exercise Wednesday and Thursday.
The exercise, named "Phantom Active Shooters," will occur both on and off post and involve soldiers, in addition to several local police, fire and medical agencies.
The exercise will test the installation's ability to respond to active shooter scenarios, which hit close to home for Fort Hood. The locations in the exercise were not released, in an attempt to make response times more realistic, the Army said.
While the exercise is happening, minor traffic delays may occur near post. And, people living near Fort Hood may see visual or audio effects that are part of the exercise, officials said. Emergency warning loudspeakers will be used to simulate "Shelter in Place" commands. The commands will be preceded by the word "exercise," and residents should not be alarmed.
The Army said the majority of the exercise will happen between 9 a.m. and 4:30 p.m. on Wednesday. It should be fully concluded by Thursday afternoon.
