If so what kind of training they would have to go through ? By training I mean the spatial and situational awareness, combat skills (this is kinda unrealistic), enough knowledge to turn any situation to their advantage etc.
Just think of the person as your average joe who financially has nothing to spend on high tech gadgets or state of the art training equipment. And doesn’t even have any support from another human being. Basically one has to train from the ground up alone.
Don’t limit the answers to just James Bond and John wick, you can even consider any realistically possible superhero or supervillain (like batman or taskmaster) as well.
So what’s your take ?
If you want to develop spatial and situational awareness, all you need to do is grow up as a victim of parental abuse. You’ll know everything happening in a 50 yard radius for the rest of your life.
Being homeless helps a bit too, especially if you experience some violence while homeless. As many homeless victims of random violence have discovered, the police will not help you at all.

I have a similar experience, although it may not be comparable to yours.
I grew up in a very strict household. My parents constantly checked up on me while I was a teenager and that too in a super sneaky way. At first I used to get jumpscared then I gradually became more aware of my surroundings (even through earphones on with music on low volume)
So I can confirm that this works. Its like using subconcious fear to boost sensory input I guess.
