A 10-member military jury sentenced Sgt. Adam Holcomb of Youngstown, Ohio, on Tuesday morning. The jury on Monday found him guilty of maltreatment of a subordinate and assault consummated by battery, but cleared him of the most serious charge -- negligent homicide.
Military prosecutors said Holcomb and seven other soldiers charged in Chen's death physically and emotionally abused the 19-year-old.
The defense argued Chen was an incompetent soldier who killed himself because his family disowned him.
The second of eight courts-martial in Chen's death is scheduled for August 13.
