An Indiana National Guardsman must answer to the federal government, about why he was found with several explosives in his car.
Andrew Boguslawski, 44, of Dearborn County, appeared in court Monday on charges of illegal possession of destructive devices.
The explosives were seized after Boguslawski was pulled over for speeding in Ohio.
During the traffic stop, Boguslawski told troopers he did not have weapons. Officers say they spotted the butt of a gun tucked between his legs.
According to a federal complaint, at least eight of the devices could have caused injuries and death to people nearby if they went off.
Boguslawski worked at an Indiana National Guard training center, and told troopers he had items for training purposes.
He has another court hearing on Wednesday.
