It will be both. I don't see much of a chance of "street fighting" in Kansas, Oklahoma, Arkansas, Utah, Wyoming and much of the mid west and mountain states. Don't be ridiculous.
In the cities, yes. Raids against “those a@@@holes” in Little Rock, Salt Lake City, Osh Kosh, Dodge City, Kansas City, etc. Punitive raids against the countryside, blowing away farms and small towns. Booby trapping roads to capture targets. Liberating grain silos for starving urbanites. Plain old assassination.

In those states it will be guerilla attacks.
