Now, as some of you know, I am working on a TEOTWAWKI novel. In this novel, a wealthy hobby-survivalist is stuck tending to a group of his friends who are traveling across the CONUS after TEOTWAWKI occurs. Two of the characters have extensive firearms training - the survivalist and an Army veteran, and another one has a limited experience hunting with his father and so forth. The other three people have very limited training, mostly limited to basic gun safety. So, how would you provide those last 3 people with basic gun training after civilization is gone? Assume that before the event, you were rather wealthy and prepared.
