For information on commissioning programs, which OPNAV instruction should you refer to?

The correct choice, OPNAV 1420.1, specifically addresses the various Navy commissioning programs. This instruction provides the most comprehensive guidelines related to the processes, eligibility requirements, application procedures, and responsibilities for personnel interested in becoming commissioned officers in the Navy.

To understand why this instruction is fundamental, it's beneficial to recognize the focus and intent of each OPNAV instruction on commissioning programs. For example, OPNAV 1420.0 is more general and may not detail the specific programs; OPNAV 1420.2 and 1420.3 likely pertain to specific aspects or updates of commissioning policies but do not encompass the entire scope of commissioning procedures like OPNAV 1420.1 does. Thus, referencing OPNAV 1420.1 will provide the necessary and precise information for anyone seeking to understand or engage with Navy commissioning programs.
