Thanks for mentioning this. A quick search turned up this book, is it the right one? https://archive.org/details/modernsurvivalma0000agui. Fernando Aguirre, 2009. The Modern Survival Manual: Surviving the Economic Collapse.

It would be really interesting to compare/contrast his account from others from Ukraine, Syria, the Balkans. What I hear in your comment is that the advice you heard was about having weapons for a strong defensive posture rather than to be used offensively. I guess the strength of both communities and gangs is in their size, they'll win out over the lone wolf fantasy.
