The report was distributed to those closest to the case but is not available to the public, according to records filed with the U.S. District Court in Augusta.
A competency hearing to determine whether Anthony Saxon, 34, can understand the charges and cooperate with his attorney has been scheduled for 10 a.m. Monday. An arraignment also has been scheduled for that date.
Saxon was arrested at Fort Gordon on June 15 after military police found stun grenades, a land mine, several night vision devices and a laser sight in his car, according to court documents.
A tipster recognized his vehicle from a theft of military equipment in April.
U.S. District Court Judge Leon Barfield ordered psychiatric tests to determine Saxon's sanity after citing evidence that suggests there is "reasonable cause to believe that defendant may be suffering from a mental disease" that could prevent him from assisting his attorney with the case.
According to an affidavit filed in U.S. District Court, Saxon told interviewers he never served in the Army but was a member of the Army National Guard from 1993-95. He was discharged because of health problems, Saxon told the FBI.
