Well, it is unknown when the Nosalises were first encountered, although, obviously, they were there for at least two — five years before Metro 2033 for them to be considered most common enemies of Metro. It should also not be forgotten that several years would have to pass before the Nosalises mutated from rats/moles/whatever they were.

Those two (Chook and Geek, named after the Arkady Gaidar book characters «Chook» and «Geck», by the way) seem to be more scientists (or just self-taught nerds) than rangers. Given that Chook clearly shows off "Lingua latina" skills (with more than likely the name he or one of his fellows made up. Since the Rangers call them Nosalises too.), it is completely legitimate for him to refer to others as "commoners" in the same sentence.

Such a portrayal of scientists (and doctors) as a bit weird snobbish guys who call things by Latin names just to show off is pretty common in Russian books, really. The "new" thing can be explained in the same way.

Have i seen a Ranger using one of makeshift guns? Hell yeah — Artyom uses them all the time! Jokes aside, probably not, but i remember seeing Melnik in Metro 2033 using Volt Driver in the last chapter while making his way to The Tower.

Also, Anna uses Preved, doesn't she? And don't forget the minigun from the D6 battle.

Browsing this wiki also pointed out that twin brothers from the Kshatriya level do use makeshift weapons — Medved and Shambler.

Though these people all are common in that they go up to the Surface, all in all, it could be concluded that The Order isn't strict about choosing weapons, although the use of AKs is preferred due to D6 having lots of them conservated.

P.S. By the way, i forgot to ask about «scavenged» screenshot. In what sense do you mean "scavenged"? If i understand correctly, it could very well be "scavenged" too. The Polytechnical Museum is not really far from Polis or D6, so the device could be brought from there.
