If you commission in to the Air Force as a non-rated officer (not a pilot, navigator, air battle manager) you'll be required to serve 4 years active duty. Pilots are required to serve 10 years. Basically it would be 8 years active (2ish years for flight school, 6 years actually flying) then 2 years inactive........
Stumbling block. For other uses, see Stumbling block (disambiguation). A stumbling block or scandal in the Bible is a metaphor for a behavior or attitude that leads another to sin.
This is a major stumbling block for many people. They question why God would be so angry about a simple census ordered by the king, and why so many innocent people had to be punished for David's actions. Because this is a major stumbling block, it is worth taking a closer look into it.
