Sure. When the military murdered and/or raped 300+ villagers in My Lai, it was a very serious offense. The commander (lieutenant) was ultimately charged 22 counts of murder, and served a very hard three years of house arrest.
As you can see, the charges are quite serious, which can exceed 3 days stuck in house per instance of illegal homicide.
If they have orders to fire, then there will be no court, they just have to fill out an after-action report detailing what happened.
