I can't speak to the Army WO's ground side, but from talking/working with a lot of former Army WOs, I don't get the impression that they are placed in the same kind of positions that Navy URLs are. I'd be interested to hear
@RobLyman 's take.
HSC and VRC (and HSM and VP, two other communities who received WOs before) operate in an independent state. I heard several times from people that operating as a detachment OIC is "command at sea" in the non-PERS board sense. A little dramatic? Probably, but the OIC and the Det MO both operate independent of a mothership. The Det OpsO has numerous responsibilities that mirror a squadron OpsO with reduced supervision. Is a WO the person to do that? Can a WO legally do that? The answer is probably yes to both, but not without some significant experience that a AW2 doesn't have.
From what I've gathered, Army WOs (at the operational level) excel at executing policy and procedure, but that strikes me as something different than what DIVOs on a detachment level do. But maybe I'm wrong.
