There are a few things about the premise that bother me.
The author's model is focused on a pitched battle in “deep space”.

Maybe I'm wrong, but I read that to mean Interstellar space.
While he touches on the relativistic problems associated with conducting warfare over Interstellar distances, he doesn't seem to take them seriously.

Let's say we were going to war with our nearest neighbor, Alpha-Proxima Centauri.
The battle would presumably take place somewhere in a vast (But relatively narrow) no man's land, centered on the midpoint between the two solar systems.

Because we're dealing with propulsion systems which are at best capable of ~0.98 C, and for practical reasons, probably a lot less, military commanders would have to move their forces at best speed, from anywhere between 2 to (You figure it out) years just to approach the theater of operations. That's not accounting for the need to decelerate, once the enemy was detected.
If you add in the logical tactic, of sprinting for a while, then slowing to get a squint at the bad guy's, (The submarine analogy) it could be many years.

If you exclude this tactic, then you're just a big: HELLO, HERE I COME. To the enemy's sensors.

Sensors will be paramount.
Certainly, but EM sensors, no matter how powerful, fall prey to the same Relativistic limitations.
Anyone have a guess as to how effective EM sensors would be on a craft moving at a good fraction of the speed of light, against a target either at rest, respective to it's frame of reference, or at Relativistic speed in a different frame?

Communications:
See above.

Weapons:
A mute point, given these conditions, and constraints.

If you were at war with your closest stellar neighbor, then hiding your Homeworld's location would be pointless.

(Keep in mind, the authors model suggests both sides are ~equal in technology)

Instead of investing all that (Tremendous) capital in a wasted enterprise, why not focuses on defending the Homeworld?

If war was certain, then draw them in, feign weakness, and extend their logistical infrastructure to it's weakest point.

Then attack.
