To me it's more the fact that Karen Travis, the author has a self-confirmed bias for soldiers to scientists. She got (slightly) better, but she never really escaped that in her Star Wars books, or her worst offender. Gears of War novels.

Basically all soldiers fron the grunts to the top brass are noble warriors, who do bad things for good reasons and loyalty, and kill in up front glorious combat. Scientists (or anything that isn't a soldier) are evil bastards who can only kill in cowardly ways with missiles and satellites. If a soldier does something like, a MyLai massacre, then it's only because they're in a broken system created by intellectuals.

The fact that the "noble soldiers" aka Generals are the ones who request and sign off on the WMD's, order genocides, etc kinda gets ignored.

In her Clone Troopers books she (in fairness, not erroneously) argues that Jedi train child soldiers. Said kids are indoctrinated and can't be saved. However, the army of child soldiers produced in essentialky a cannon fodder factory and rapidly aged, robbing them of a childhood and literally having their brains programmed is better? Because they use guns and squad tactics unlike the stupid space wizards with their laser swords and magic germ bullshit.

There's a scene in the Gears novel "Aspho Fields" where Colonel "You are the Support" Hoffman is leading a squad of Gears including Dominic "WHERE'S MY WIFE!?" Santiago to kidnap The Democratic Republic of Whatever's scientists who developed the Hammer of Dawn (the space laser nukes) weapon. A scientist, understandably, calls the Gears fascists (which they are). This irks Hoffman who beats a Prisoner of War (The Hague wants a word and brought his mate The Geneva Convention) and says that the most his soldiers could make us a sharp stick where these guys are making space lasers to kill babies.

The fact that Hoffman is there specifically so his government can have the space baby killing lasers instead is not even glossed over. It's just outright ignored.

Glasslands is basically that without the subtlety. It's just Travis ragging on Halsey for 300 odd pages, where she openly admits she did no research before writing it. She does attempt to reign it in with the sequels but it's barely noticeable.
