If I'm a soldier and got pulled over and charge with open container will I get in trouble even if I'm not drinking at all?

I'm driving to on post Fort Riley, KS. for giving my friend his alcohol bottle back. I didn't mind so I rushed and put it in the back seat underneath the passenger’s side. When I got over, MPs did a random inspection. They found the bottle closed tight but they said its still unsealed bottle. I wasn't drinking so they realize not to give a BAC test which that surprise me. They I don't have to go to court or I could fight it. Can I get in trouble in the army even I didn't get a DUI?
