The plot fictionalizes weaponizing artificially intelligent robots.
The technology perspective (ca. mid 1980's) already feels dated, and the philosophical angle lacks the profundity of, say, "The Forever War", which covers some similar terrain (the military establishment equating warriors/individuals with machines) and which remains more topical despite having been authored at least a decade earlier.
The book is clearly reaching for a WOW! moment, but fails, at least comparatively, in both scope and depth.
It's a quick and entertaining airplane or beach read.
But if I had to do it over, I'd re-read Haldeman's "Forever War", or, more likely, give "Armor" or "Old Man's War" a try.
