"The Art of War" displays about 40 images at the University of Dayton's McGinnis Center through mid-December.
Busch — who plays detective Anthony Colicchio on the HBO series The Wire, and has appeared on The West Wing and Homicide: Life on the Street — will talk about his photographs at the center
He also will show new images he shot during his most recent deployment, which ended two months ago.
Those are part of another, "darker exhibit" titled "Occupation," he said.
"I was wounded this time and had two cameras destroyed by explosions during that deployment," Busch said Thursday.
The exhibited photos "do both the American military and the Iraqi people a certain unique justice," said Busch, 36.
"My photos are not pro-war; they're not anti-war. They don't say the war is a mistake or it is the best thing we have done. What they do say is, 'It was war, it was Iraq and we were there.' "
