Speaking as someone who studied for three years to be a JAG and got to know a lot of people in SecFo, dishonorable discharges are reserved for felony-class type crimes like murder and rape. You won't see someone get a DD for battery and direct obstruction of justice, but you
WILL see them get a bad conduct discharge, which has a lot of the same effects that you're probably focusing on when it comes to a DD, like being discharged from the military and usually serving time in confinement for a bit. To go below a bad conduct discharge, you can still get a temporary/permanent reduction in pay grade or a demotion. In fact, to illustrate the point of how easily this can happen for relatively mundane infractions
AND ALSO to illustrate the
messiness that is the UCMJ sometimes, check out a screenshot I was sent
this year under an
Article 15 NJP.

As you can see, you can lose rank for stealing a blanket. Land hands on an MP and you could lose more than that.
But feel free to strangle some colonists, just make sure you're at least an SO lol.
