Relieved of his command of the Vicenza, Italy-based 173rd in March 2011, Johnson could face multiple years in prison and a dishonorable discharge if convicted of all of the counts against him.
However, he pleaded guilty to most of the charges.
The former commander of the US Army's 173rd Airborne Brigade is going on trial over accusations of fraud, bigamy and conduct unbefitting an officer.
The court martial of Col. James Johnson III is scheduled to be held before a panel of officers in western German Kaiserslautern on June 16.
He is also accused of an alleged long-term extra-marital affair he had with a woman he met in Iraq, while they were both living in Europe.
