Lt. Col. Jon-Paul Depreo, 42, was fired in January 2023 as commander of the 46th Engineer Battalion at Fort Johnson, La. (U.S. Army)

Lt. Col. Jon-Paul Depreo went from commanding an engineer battalion at Fort Johnson to prison-bound in less than six months after he pleaded guilty Monday to charges of assault and conduct unbecoming an officer in a courtroom at the Army post in Louisiana.

Military judge Col. Maureen Kohn sentenced Depreo, 42, to spend two months in prison, which was consistent with the terms of the plea agreement, according to a statement from Shelby Waryas, a spokeswoman for Fort Johnson, formerly Fort Polk. He pleaded guilty to one count of assault consummated by a battery and one count of conduct unbecoming.

He was originally charged with one count of abusive sexual contact, one count of maltreatment of a subordinate, and two counts of conduct unbecoming of an officer for his alleged actions, Waryas said last month when Depreo’s case posted to the Army’s online court docket.

Waryas did not say what led to the charges against Depreo.

Depreo took command of the 46th Engineer Battalion on June 17, 2021, and was fired in January, according to Fort Johnson.

Within Depreo’s first month in command, Command Sgt. Maj. Jeremy Compton, the unit’s top enlisted soldier, was fired amid a separate criminal investigation. Compton pleaded guilty June 1 to distributing child pornography, adultery and sharing explicit photos of himself while in uniform. He was sentenced to 20 months in prison.
