Almost everything is scavenged.
Full-body ranger armors are from Desert Rangers and some pre-war units, while Power Armors from dead BoS member.

Well, the NCR does not have vehicles, as far as I'm aware. Pretty much all combat is done on-foot.
FO2 pretty much contradicts this outright. NCR was CREATING their tech, they weren't scavenging like the outlying communities which they attempted to absorb were still doing. New Reno, prior to joining the NCR, was both scavenging (like the Wrights were attempting with SAD for an undisclosed period of time with multiple conscripts) and making deals (like the Salvatores with the Enclave) and otherwise just outfitting themselves with wasteland purchases, wherever they could be obtained, by simply having the currency to buy anything they want because the casinos drained every visitor dry. How much of their activities changed after being absorbed into the NCR isn't specified, but we can be sure the Salvatores' deal with the Enclave was ended.
But Shady Sands, the capitol of the NCR, was producing its own tech, with help from the Brotherhood (prior to the BOS's rebellion and the subsequent war between the 2 powers). By the 2240s, Shady Sands a fully armed police force with Guass Rifles, Bozars, some of the best Shotguns that could be found in the game. The NCR Rangers, which began as a liberation movement before becoming indistinguishable from the rest of the NCR's military, were fully outfitted with Combat Armor and heavy weapons. These were more than half a century before the Ranger Unification Treaty, so the Dessert Rangers weren't the source of the NCR's combat armor.
Like the BOS during FO1, it was implied that these were productions, and the only real scavenging that Shady Sands required was computer parts from Vault 15 to keep their industries going. But the nation, as a whole, was NOT technologically bereft of progress and below what the US had during WW2. Some of their states relied more on scavenging than others, but plenty were able to produce their own wares as a bustling business. The wealth that the country accumulated was put into SOMETHING. NCR was capable of some level of production, though they weren't able to create the highest level of technology, which they scavenged.
At best, the NCR's level of tech became strained following the insurrection with their former allies in the Brotherhood. But they didn't rely on scavenging, and they had plenty of vehicles. We merely see a much less-outfitted NCR in FONV because the Mojave was frontier country, to them, and because of the politics of the war with the Legion, their outposts weren't being maintained with the full supplies at the nation's disposal. They weren't able to produce any Power Armor of their own, but neither could the Brotherhood, so their Power Armored Troopers were equipped with scavenged and repurposed equipment, but this was not the only method the NCR had to outfit its military.
The level of equipment and the method for their acquisition in your story would likely depend most on where the training camp is located. If it's near Shady Sands, then it probably gets outfitted with new creations from the capitol. If it's somewhere on the outskirts of the Core Region, then it wouldn't seem unlikely for them to be the results of scavenging trades.
