You can't ever bump someone out that is junior to you if there is no vacancy.
If there is a vacancy, then you will be awarded a spot, and everyone below you will bump down a spot.
The most junior guy today will bump down to the most junior guy after the vacancy award, making room for you wherever you fall in the FO list for that base.
