Montage

To my knowledge, premils usually regard Rev 4-22 as a chronological sequence.

It's interesting in that regard to consider how Rev 12, especially 12:7ff. fits into that overall chronology. To begin with, it arguably refers to the life and afterlife of Christ. That's more than halfway through the narrative, yet it takes its point of departure in the 1C, with the life of Christ.

In addition, the passage reads like a flashback to the primordial fall of Lucifer. Yet, in context, it is arguably referring to his loss of power after the Resurrection and Ascension of Christ.

So we have an event in the present and recent past (recent for John) that's depicted in terms of the distant past. A historical description using a prehistoric event as the lens–like a montage. 

But that, in turn, raises questions about how we should construe a similar event in Rev 20:1-10. I'm not suggesting Rev 20 recapitulates Rev 12. But there are studied parallels.
