Notice, too, how neither side really has a standing army. A-M had a bunch of mercenaries, and the tribes of Klatch are fragmented.
I also detect a certain amount of criticism about how politicians manipulate the lives of soldiers, or more correctly, sacrifice them. I certainly got that impression from the A-M Miles Gloriousus, Lord Rust, and I don't doubt that the Klatchian leaders would be all too willing to sacrifice their own men to glorious casualties, although they seem a little more inclined to strategic thinking.
Actually, on a bit of a tangent here, but themes about soldiers being sacrificed and diddled over by pollies seems to run throughout fiction. I mean, look at the Metal Gear series. In fact, I've just noticed a number of similarities between Metal Gear and Jingo. They both take a dim view of political sacrifice of the soldier. They both emphasize tactics over rushing in, guns blazing or swords flashing. And they both shoot down jingoistic patriotic BS, especially in later installments where Metal Gear is concerned. I mean, the villains, overall, of the Metal Gear saga are called 'the Patriots'. And they both have a ditzy genius in denial that he is creating things that are capable of mass destruction.
And there's another tangent. I wonder if Leonard of Quirm would be able to build the Discworld equivalent of a Metal Gear, and if so, what would he call it with his usual skill? The Two-Legged Walking Catapult Thing?
Sorry. My mind goes to some weird places and makes some weird connections.
