Your country has been invaded by another country. How do you (not an organisation) resist?

A relatively short question.<br><br>So, a totally hypothetical example. I live in New Zealand, and our military is basically just normal people who either volunteer or are called up at random. Our military doesn't have professional full-time soldiers like some countries. <br><br>If New Zealand was invaded by Japan, which let's just say has a powerful military, then they would easily win. Our military doesn't stand a chance, and also our government would probably surrender as it would be easier to work with the Japanese than to fight them.<br><br>But there are many reasons why I'd want to resist. I don't want to lose my country to another nation. My family has lived in New Zealand for generations. It's our home. I have no desire to leave. <br><br>I'd want to fight back, but I'm not in the military. I have no training or experience. I'm just normal person.<br><br>So how would I, and others like me, resist? The question is about what we would actually do. What action would we take?<br><br>What forms of resistance would I use?<br><br>Could I adapt my skills for the purpose of resisting?
