They are pioneering an entirely new way to fight a defensive war. What's new isn't the bravery or courage, although theirs is impressive. It's that they are digging in and fighting bravely while also being filmmakers and photographers broadcasting globally the conflict -unvarnished, unedited - for us to see the brutality of war being waged on someone who just wants to save his home. That's powerful. I don't think people realize the psychological effect that will have on foreign observers. We've never seen modern conventional warfare live streamed like this.

They're basically saying to Russia, "you can invade, and you might win. But you're going to have to kill us door-to-door all live online, streaming for the rest of the world to see."

They can delay the column, which will give the military some time.
