Good effort there!
I hope chapters 1-4 will provide some context to the war. It
seems war is not declared yet, and I'm wondering why the waterworks
was seized and if there is any wider war. (if this is the only
provocation, and if singapore is destroying the malaysian whole air
force. since malaysia seems so unprepared for war, it seems all
they want is the waterworks- or they would have shelled all of
singapore's runways first thing, mined the straights, launched
anti-ship missiles from planes flying in their own airspace etc.
You get the idea. Most people try to achieve big surprise gains in
war, beyond seizing a little pumphouse.)
Keep it coming, we will be interested!
3rd paragraph of chapter 5- I think you've read Fist of God.
