It doesn't really impact your life in the civ world aside from government/DoD jobs. Depending on the circumstances, you may or may not want to speak too much about your military service.
The main kicker is that you don't get the GI Bill, so it's important to shoot for that honorable if that's your goal.
Other than Honorable and BCD (Bad Conduct) are the ones that you really don't want to get. You do have to *really* fuck up to get those, like assault or abuse of authority/trust.
You forfeit most of your benefits and probably shouldn't mention your time in the military, lest prospective employers do some digging.
Dishonorable is equivalent to a felony, but is generally reserved for rape/murder/mutiny/AWOL, though most AWOL people get OTH discharges since they run away stateside.
