<human>: Assuming everyone in the town were totally down to be helpful what would be your main resources, how long could you last, would you most likely be overtaken? Let's assume the force sent to wipe you out changes from the city's size (population/land area) where and what would be your weak spots? 
Example: I live in a northern Oklahoma town population approx. 25,000 people mostly retired or otherwise old folks, highschoolers, maybe a few hundred 20-35 year olds. The best I could hope for for supplies would be maybe a few weeks, we have only 3 food marts about 7 scattered restaraunts, and the rest are clothing stores and medical facilities. So our food would probably be our weak point. As for defense we really only have about 3 main roads into the place and a lake blocking of a pretty big part of one. I'm sure being in Oklahoma we'd have plenty of guns. I'd say overall we could hold off a force of atleast 300-400 militarized men for 4-5 weeks.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Trapped in your town no outside assistance coming a force of 1/4 or more of your population militarized are coming down on you, what do you do as a town to survive, and how long could you last?
