PCS or Separate

I got a short tour assignment to Turkey and will arrive with only 6 months left in my contract. I am thinking about doing the full assignment or separating from the military. On one hand I get to travel but on the other I can make much more money outside since I have my A&P. My main CSS guy is on leave so his fill in doesn’t know everything, but he was telling me that I would have to extend my contract regardless since Turkey has already been assigned to me. I haven’t gotten a chance to talk with MPF but was wondering if y’all had some input on whether that is true or not for me being required to extend giving me no choice in the matter.
