This review is more about the current state of the Star Force Series in general than this particular book. When the series started out, the protagonist was basically a guy who had everything he cared about stripped from him and he was struggling to fight back as best he could. In other words, he was fairly likeable and entertaining.
Unfortunately, by the time of this book, the protagonist has degenerated into a very unlikeable person. He has become a micro-managing bully. He is the only one with the purity of vision and the sheer intestinal fortitude to save the day and conquer all.
Yet, he, himself, never learns. The same combat mistakes (e.g. having his Marines dig it only to have the enemy attack his position by tunneling up from below) are repeated over and over again. His weaponry is constantly being designed to fight the last war. His subordinates are all browbeaten and without backbone.
As for his military tactics, they essentially boil down to charging heedlessly into trouble and then trusting improvisation to save the day. There is no grand strategic plan to win the war or even a tactical one to win the day. Indeed, there does not seem to be any effort made to develop even rudimentary squad or unit combat cohesion among either his Marines or Navy. Mutual support, except of a very basic individual basis, seems to be non-existent.
The worst, however, is his total disregard for the lives of his subordinates. At the time of this book, he has at his disposal a severely limited pool of humans. In other words, humans are a limited, irreplaceable resource. Yet, he prolifically spends human life without any regard for the consequences. All he cares about is achieving his immediate aim. The thought never occurs to him that, if he runs out of people, the war is lost. He is not a leader to whom any sane person would wish to be subordinate.
All in all, it is truly hard to enjoy a book wherein the protagonist is someone who you really want to frag.
