What is it like for an OC/T (Observer Controller) at Ft Knox?

I assume that you will be going to 4th CAV. I was in that unit until 2013 when we had the PRT Training mission. It was pretty fun and rewarding but we were gone all the time. I know they no longer have that same mission and I'm not sure what they are doing now but you can expect to spend a big chunk of your time gone TDY.
