Idaho National Guard spokesman Col. Tim Marsano says the 190th Fighter Squadron will be training through July 25 at altitudes between 10,000 and 15,000 feet.
He says the aircraft don't have high-performance, afterburning engines and produce about as much noise as a small commercial jetliner. Marsano says there will be no live ammunition aboard the Thunderbolts.
Residents might see "Tactical Air Command and Control Specialists" and their equipment on Boise streets as part of the "Urban Close Air Support" training.
Marsano says the training is important for pilots flying the specialized combat aircraft.
