FORT BRAGG, N.C. — A military jury recommended on Tuesday that a sergeant be sentenced to 30 days in prison for mistreating and assaulting Pvt. Danny Chen, whose suicide in Afghanistan last year drew attention to the standing of Asians in the United States military.

The jury also said the sergeant, Adam M. Holcomb, should be reduced one rank, to specialist, and be fined $1,181.55.

Sergeant Holcomb had faced a sentence of up to two years in prison and a punitive discharge.

On Monday, the jury found him guilty of two counts of maltreatment and one count of assault. But he was acquitted on charges of negligent homicide, reckless endangerment, communicating a threat and hazing.

The verdict was a blow to military prosecutors, who had sought at the court-martial here to show that Sergeant Holcomb’s treatment of Private Chen, which the prosecutors said included hazing and racial taunts, led directly to his suicide.
