Welcome Sandy! You will definitely want to post your question over in the bootcamp group - you will get answers quicker over there.
Here's some info I have posted regarding Sandboxx. You can use it BUT IN BOOT CAMP ONLY. Click on the link:
Once your son is out of boot camp you will want to delete the app - it violates OPSEC.
Your SR should get another call (could even be multiple) but it just depends on how his division is doing. No guarantee's on anything!
Again, come on over to the boot camp group and you'll find answers to these and many more questions there.
Hang in there!
