So the score still is exactly two references to UFP Starfleet not being a military organization (one of which comes from an alternate universe) - against dozens
of lines referring to Starfleet being "the military", having "soldiers", and being the one force identified as fighting wars for the Federation. The evidence really is overwhelming against Starfleet being "nonmilitary"...
...Except for that one moment in "Peak Performance" - a moment falling between the explicit militariness of O'Brien's employer a few years earlier (2362, apparently) and the explicit militariness of the same organization a few years later (2375 at the very latest). Should we really treat this as a time window? Or rather as an outlier and an anomaly?
