Final answer:
The minimum active duty obligation for OCS graduates varies depending on the branch of service, typically ranging from four to eight years.
Step-by-step explanation:
The minimum active duty obligation incurred by OCS (Officer Candidate School) graduates varies depending on the branch of service they join. In general, OCS graduates are required to serve a minimum of four years on active duty. However, some branches, such as the Navy and Air Force, may have longer commitment periods.
For example, in the Army, OCS graduates are typically required to serve four years on active duty and four years in the Individual Ready Reserve (IRR), for a total of eight years. The Navy also requires a minimum of eight years of service for OCS graduates, with a combination of active duty and reserves.
It's important to note that these are minimum obligations, and many OCS graduates choose to continue their military careers beyond the required commitment.
