Final Storm Chapters

Working our way through The Final Storm it's occurred to us that the chapter about sub-ops should be rolled into the overall chapter on northern operations.

Previously the northern-ops had two focuses, A and B. So the chapter went back and forth, A then B, A then B.

Of course folding the sub-ops into said chapter will lead to two new subjects, C and D. So you'd have something like A then B then C then D followed by A then B then C then D.

You tell me reader(s). Which is less confusing? Which is better?
