The next civil war won't look anything like the last one with two sides having geographic boundaries, distinct uniforms, and a clearly defined chain of command.
It'll be like Syria, factional warfare. Smaller, loose-knit and fluid organizations, many with little military training or discipline, poor structure and leadership.
These organizations will have different goals and objectives that shift over time and situation and even those who share the same ideology will have squabbles over egos and leadership. Groups with opposing views will align with each other to vanquish other groups and then find themselves fighting each other once again.
Then add to the mix a multitude of armed bands of marauders and various criminals who are just out to rob and rape.
It's gonna be fun!
Targets of opportunity.
Heck, yeah!
It sounds like "The Walking Dead."
4th Generation Warfare. The decision makers and the enablers in the media will be legitimate targets, just as the Tories were. It will be a lot less force on force of large formations and more fire team and squad hits.
