If I have issues with not being contacted by a sponsor for my next unit, is there someone I need to call or something I need to do?

I would try to find the training room number to your gaining unit or battalion staff duty. In my 20 years I did that a few times; due to the occasional field training, schools, or other issues your sponsor might encounter. It’s always a good idea to just contact your new units training room or battalion staff duty. Half the time if there is no contact with a sponsor; reception will always be there to take care of incoming soldiers

If you’re coming to Campbell you’ll spend your first two weeks or so at the Kalsu Replacement Compny located on Desert Storm Avenue across from the LaPointe Soldier Clinic. Check in there and they will get you squared away with all your inprocessing of the installation. They will help you get in contact with your new unit but I wouldn’t sweat it until you finish your two weeks or so in-processing. Replacement Company: [login to see]

Also look at this page to figure out what you need to bring when you sign in to Fort Campbell:

Do you have your orders yet? They may not have you on their manning roster yet as an Incoming Soldier. There should be a POC on your orders, I would call them if you really need too. If you know your Unit already call the Staff Duty Number or Contact the BN S1. Sometimes you go to a Post Level Inproccessing Station and may get routed to a different Unit based on Unit Strength or Pending Deployment. Sponsors sometimes don't know until the last moment that there is a New Soldier coming or they may be engaged in an FTX or other training.
