In the video below, S2 Underground talks about the military practice of Intelligence Preparation of the Battlespace. This is an analytical process for providing verified information in order to plan and execute operations. If you are familiar with Forward Observer‘s Area Study classes and videos, then you know that Forward Observer has adapted these military practices to civilian intelligence for preparedness and SHTF operations.
S2’s video is a high level overview of the IPB process, but you should be able to glean some ideas on how it would apply to civilian preparedness.If not, then maybe it is helpful to think about operational environment as your block, neighborhood, or town. Threats could be drug cartels, foreign armies, hurricanes, EMP, or power outages. And then you can decide your worst case scenarios from there.
