Fake fan, ncr was adapting power armor for minimal training use in heavy units during the events of NV.

I will say, part of the narrative of the NCR's millitary strategy was removing the servos, power, etc from the suits and just using them as raw armor. No training needed as the PA was more like a vehicle to pilot, but no actual strength or agility benefits, leaving them highly immobile, and thus deployed as shock troops guarded by more mobile units, or bodyguards themselves for high-ranking officers like General Oliver, as they can't move long distances. This dependence on vast networks of logistics in order to field the NCR Heavy Infantry led to specialization of roles.

Using Power Armor plating on the Rangers, who are supposed to be highly mobile scouts and self-sufficient wasteland experts, doesn't make much sense. If this is powered power armor, then maintaining the suit integrity makes more sense than chopping it up, if this is unpowered, it's aesthetic in purpose to draw on NCR Ranger nostalgia, yet works against the purpose of the division of the NCR's two-pronged millitary, the traditional millitary and the Rangers, the Take-And-Hold and the Guerilla experts respectively. Both served different roles in the NCR's Imperialist aims, and both were critical to its rapid expansion.

The reason the NCR Ranger Armor itself is iconic is more that the NCR actually did adapt to developing units suited for vast expansionism and far-reaching scouting, which is why they were able to overtake the Brotherhood, who were more immobile, and were able to hunt down the remnants of the Enclave. Unpowered Power-Armor for Rangers implies a drastic change in unit purpose.

I hate to say it, but as a New Vegas turbo-nerd, this doesn't make sense, I would rather have seen collaboration with the Shi in getting the Powered Power Armor more widely produceable and trainable for NCR's traditional millitary units, which would be an expansion on their millitary capabilities against the Brotherhood, rather than the Ranger side of the millitary, which is more for far-reaching scouting excursions and assassination/sabotage, guerilla fighting than the take-and-hold of the traditional millitary wing. This allows for cool new area to be tread in concepts like NCR developed PA, while building naturally on the lore, in a way that acknowledges the real threat of the Brotherhood's Power Armor.

Such a shift towards more stationary yet strong units would also play with the TV show's narrative of NCR fracturing, turning more to trying to hold the Republic together than expanding outward, learning from the relative staying power of the Brotherhood.

Thanks for coming to my Ted Talk.
