?? you need to be more verbose with your queries - what part is confusing, the word separation or the part where someone’s kicked out of gov’t service?

Convenience of Government (COG)

A reason for separation from Active Duty which allows discharge before completion of the obligated period of service and is a factor in determining eligibility under Chapters 30 and 32. Service members must have served a minimum of 20 months of a two-year enlistment or 30 months of a three-year enlistment in order to retain eligibility when released for COG.
