Off subject, but does anybody have any idea if prior service is vital while applying for DCO/IW/IPIntel?
It depends on your definition of vital. It is not vital, however you are at a significant disadvantage without it as the board directly considers prior service as a primary indicator of success as a Naval officer (so long as the panel interview and OIC endorsement also reflect this). Evidence of this is from the last DCO board; more than 85% of those selected had some form of prior service between 4 and 12 years with the majority being prior enlisted non-commissioned officers from all of the services in the Intel/IW fields. The most competitive candidates are usually prior enlisted in the IW/Intel fields from the Navy or other branches for at least 4-8 years with demonstrated leadership experience, positive fitness reports, and a graduate degree (IP was different). There is no formula for success, but there is certainly a formula for being the most competitive in the eyes of the board, and this is it. The only situations where being prior service would hurt a candidate in the eyes of the board (not considering those with derogatory information, as they aren't competitive in the first place) is if the candidate had 15+ years prior service, at which point the board will assume the Navy wouldn't get much return on the investment. Prior service experience as a non-commissioned officer is exactly what the Navy is looking for to fill its "direct commission" ranks -- people who are proven commodities with significant military leadership experience who can hit the ground running, otherwise what is the point of a DIRCOM when we can just send them to OCS like everyone else. There are certainly exceptional civilian candidates with no prior military service, but they are the exceptions and not the norm (i.e. FBI agents, experienced analysts in the IC at the GS13+ level, civilians at ONI, etc.). The IP field is a bit different, as most people competitive for this who have the necessary expertise are usually from outside of the military and federal government.
