Weapon wise so long as it exists roughly within Fallout timeline its a safe bet that it exists. So yeah stuff like FAL, AR, and AKs are available. You also have other stranger weapons which is how you end up with energy weapons and other exotic stuff. It's worth noting that their Fallout military moved away from AR platform and adopted the heavy duty very rugged 10mm pistols/SMGs instead of .45 or 9mm. Combat armor and energy weapons were available to the public so that is a thing too. Really the only thing the public didn't have access to was power armor and even than they were already phasing it in for 'police actions'(via outdated frontline power armors being repurposed) and such. Not to mention exoframes which totally do not count as power armor.

Cletus and everyone else only knows about the surface facility and military base. Everyone knows though that isn't the whole truth but don't know what exactly was hidden underneath. The surface facility kind of got carpet bombed as it was the only obvious military installation while the tactical bunker busting nukes were explicitly targeted the facility underground and the bunkers that were set up around it weren't yet fully completed yet(hence why they were undermanned and construction materials were available).

The base in question was unnamed because it wasn't 'officially' completed yet but everyone went with the codename for it being Snapping Turtle Bastion. As it used to be housed in a valley with a lake.

Cletus can tell she VERY aggressively modded herself out to a frankly extreme degree even by prewar standards. Especially under current conditions, by all rights she shouldn't be in such 'amazing shape'. However he doesn't have the medicine and science skills high enough to figure out exactly what she did to herself. His repair is high enough to know that she did not go the cybernetic route. Its to the point that Cletus has doubts on how exactly 'human' she remains.
