How to get to Knüllkaserne?

Hello, I'm about to begin my service in the German Armed Forces (Bundeswehr), which will start at the barracks in Schwarzenborn. Since I still rely on public transportation, I started looking for a suitable connection, but couldn't find one. I was able to find a bus stop using an app, but I'm not sure if it actually exists. I'm hoping someone who has been there, or lives nearby and is familiar with the local bus schedules, can help me.

Thank you.
