No. If it was a pre-award in PBS, then you get 4 hours credit for each day away towards meeting your min guarantee. Your guarantee will be adjusted to what your remaining flight schedule is. If you dropped the 2 weeks after the PBS award, you lose 2.5 hours of credit towards guarantee for every day away. So if you were on MIL Leave for 14 days, you're new guarantee would be 75hrs-14days*2.5hrs=40 hours min guarantee.

Hope that helps. Feel free to PM me if you have any other military related questions.
