Okay, first off this book is really two separate stories, and you can start by just totally throwing the second one away. It reads like one of Ray Bradbury's weird "good old boys on Mars" stories from The Martian Chronicles, full of yokelisms like "gubment" and "a quiet, respecful feller" and "the sheriff's deppity" and "fifty or a hunnert;" and non-PC descriptions like "he dropped to all fours and advanced in traditional Wild Injun style" - you get the picture. The difference is that Bradbury has the excuse of having written in the late 40's, whereas Laumer wrote this nonsense in 1985.
BUT...the first story does have some interesting things going on. Laumer plays with style here, telling the whole story in single paragraph snippets of dialogue, ranging from generals to senators to factory workers to terrorists to aliens to the inner monologue of the sentient Bolo battle tank itself. Plus, Laumer makes some ahead-of-his-time observations on topics as diverse (and currently relevant) as how isolated terrorist attacks are the best way to fight a vastly superior military power, the inherent unpredictability of artificial intelligence, and even "the possibility of synthesis of artificial metals, which is to say plastics with metallic properties" - which was actually pretty prescient, since back then that whole field was still called "metallurgy" and not yet "materials science."
Unfortunately, the above positives aside, Rogue Bolo suffers from many of the same flaws as much of Laumer's other work. His characters are either consistently bland, or else one of only three distinct (and frequently-repeated) voices: (1) hard-boiled futuristic private dick, which he writes pretty well; (2) redneck rube, which he writes terribly; and ALL CAPS ALIEN, which in books like this and End As a Hero is just painful: "YOU ARE DIRECTED TO DISPATCH NECESSARY FORCE TO MAKE CONTACT WITH THE AUDACIOUS ENTITY WHICH DARES INTERFERE WITH MY EXALTED WILL." Also, for every decent idea he might have about the things to come, he totally flubs all the easy calls. His characters still "dial the phone" and say things like "pass the biscuits Marge," messages are still spit out on little strips of paper, etc.
But most problematic (if not laughable) is the idea that the various generations of Bolo technology will continue to be used so very far into that future, (i.e., well into the 30th century). He describes some of the Bolo models as serving on the inter-planetary front line for centuries at a time with only minor updates. Yet even writing in the mid-80's he should have known that NO military technology can survive anymore for even a few decades. I mean, just look at the changes since this book came out, with the introduction of stealth technology, drones, cyber and space weapons, etc. - and then try to anticipate where we'll be in another 10 years, much less 1,000...
I've heard about Laumer's "Bolo" books for as long as I've heard of Laumer himself, so am glad to have finally read one. But based on this sample, one is probably enough.
