Final answer:
The minimum active duty military service obligation incurred by MSC IPP selectees upon commissioning can vary, but generally, it is three years.
Step-by-step explanation:
The minimum active duty military service obligation incurred by MSC IPP selectees upon commissioning varies depending on the career field and branch of service. Generally, commissioning through the MSC IPP (Medical Service Corps In-service Procurement Program) requires a service commitment of three years of active duty service. However, this can vary and some selectees may have longer or shorter service obligations.
For example, in the United States Army, MSC IPP selectees are typically required to serve four years on active duty. In the United States Navy, the service commitment can range from three to five years depending on the specific career field.
It's important to note that these obligations are subject to change and can be influenced by various factors such as changes in military policies and personnel needs.
