In my world, there was a brutal nuclear war, killing off a large, large amount of humanity. While the (former) working-class and blue-collar survivors spent a century fighting and scavenging in an irradiated desert, those who could afford to do so went underground, into large underground shelters.
After 150 years of deliberating and waiting, three scouts from the downunder are about to embark on a rediscovery of the surface; my question is, what supplies would they need? What supplies would be necessary for subterranean survivors to adapt and survive in the post-nuclear wasteland, and what training could they do in preparation before they leave?
Threats of the Waste
UV: These people spent their entire lives underground, in a climate-controlled dwelling, and now must emerge into an environment with a sweltering desert and depleted ozone layer.
Thirst: Simple; there is very little clean drinking water, and they'll be out for months; they need a way to secure water for a long, long time.
Wildlife/Other people: The creatures and people of this world are hyper-aggressive compared to their underground counterparts. They'll need guns that are easy to use, powerful, and reliable (Bonus if it uses ammo that can be plentifully scavenged).
Civilized communities: These towns and settlements scatter the Wasteland, and while they act as safe havens they are usually limited in technology, only having the ability to produce 1800’s era supplies, and scavenge anything else.
Radiation: Ambient radiation levels in the environment have increased, and there are some areas “hotter” then others. The locals are adapted to it, but these guys aren’t. Still, it isn’t too much a threat.
Technological level- as of now, answer this question as if these people are operating wth modern day technology.
