Introduction to Planetary Defense bases most of its strategic and tactical assumptions on asymmetric warfare - that the invaders would have a significant technological advantage (starfighters, mecha, phasers, etc.) and that the defenders have modern military technology with all the inherent limitations thereof (mostly logistical). For the most part, the book veers in the direction of "we need a government agency to prepare for hostile ETs" with a fair bit of technofetishism. Interestingly enough, the authors skirt the issue of insurgency, which is where you'd think an invasion would end up after the first attack.
Relevance to Fenspace? I don't know. With a little tweaking you could probably use it to model a intra-human conflict, maybe. I'd have to go back and reread the silly thing.---
