I'm in a similar situation, I'm deploying in 2 weeks. My CC contacted the board folks to deconflict my class dates with the deployment. I'm not sure if they moved my class dates because of it or if they were already this late, but he told me I'll be heading out sometime mid/late October. This conversation was a couple weeks ago, but I'm quite sure I remember him saying IPT is after PCSing. He wasn't told which base I'm going to though. But if you haven't already, you should let them know you're going to deploy so you don't have an issue with your class dates
