War is a continuation of policy by other means. It is not merely a political act but a real political instrument.
   — Karl von Clausewitz, Industrial Age Strategist, Old Earth

In this enormous chessboard of a battle, we were insignificant pieces, dwarfed in size and firepower compared to the vast horde of the coherent ship-swarm that was the local spatial manifestation of Caretaker. Thousands upon thousands of spheres ranging from millimeters to kilometers across, clustered together into functional units only vaguely analagous to what baseline humans might term dreadnoughts, capital ships, transports, cruisers, destroyers, surface bombardment, close-orbit supremacy gunships, ground supremacy gunships, mechanized armor, infantry, synsects, and nanoswarms....

With EMP and microwave saturation complete, unseen even to my expanded vision (taken from the locally-centered exponential weighted sum of the total available sensor platforms and processed for realtime tactical information), a constellation of microspheres and assorted odd shapes resembling ancient biological specimens fell: a giant, invading nanounit plague settling around the volume of the planet, smothering all resistance.
"Even with your limited memory, you must recall seeing this sort of thing dozens of times."
"Yes, Cara, and as I recall with my feeble mentation, you never use exactly the same tactics twice, yet the endgame always looks the same."
"Well, you appreciate that very limited simulation of warfare invented by your forebears called chess? Even that relatively simple game has more moves than can be easily totalled by your consciousness."
"It still always looks the same, or nearly so. But then, I suspect you don't unfreeze me until the endgame."

  Every star is separated from every other star by a distance on the order of light years, and so all information any one star-system can have about its neighbours is years out of date. This makes each star system paranoid about what the others are thinking and planning, so they have to assume the worst.

• Refutology War - Text by Anders Sandberg
  A minor low-violence war between the Refutologists and Faillance 8496-8513, mainly fought among minor Inner Sphere worlds. The Faillance was a trade-prognosis cartel culture that had emerged during the fragmentation of the ComEmp. As a counter to its growing influence were the Refutologists, skeptics and analysts of competing trade cultures. Among a number of minor worlds their conflict escalated due to memetic manipulation into full-scale proxy war (on the major worlds local governments had no problems preventing such conflicts). The war led to the breakup of Faillance (and the few formal Refutologist cartels) due to economic sanctions; the resulting Faillantau either dissolved over time or became minor local government religions.

• Salt, Salting - Text by M. Alan Kazlev
  In this context, when a biosphere (usually a large one, like a planet), is poisoned to make it uninhabitable (c.f. ecophagy). A subcategory of this is when a world or habitat is selectively poisoned in such a way that it becomes uninhabitable for the original natives/colonists, but is now inhabitable by the poisoners. This might be accomplished through climatic change, chemical processes, alteration of atmospheric albedo (or other radiation increasing or decreasing measures), or possibly other means. Halophiles find the human term for this perversity particularly ironic.
  
• Scale War - Text by M. Alan Kazlev based on the original by Hugo de Garis
  War occurring between protagonists of a different speeds and component densities, e.g. between (predominantly) baseline/macrotech and nanoscale/nanotech, or between nanoscale/nanotech and picoscale/magtech. Inevitably the denser, faster tech will always win, unless the disadvantaged side gets help from a friendly AI God.

• Smart Weapons - Text by M. Alan Kazlev, from Anders Sandberg's Big Ideas Grand Vision
  Weapons with have varying amounts of intelligence in them (rarely more than turingrade). The simplest Smart Weapons link to a control-command subturing and give the owner the ability to shift between types of ammo, see through the aimpoint camera etc. This kind of connection is necessary for use in teamware, and is practically standard among even the simplest baselines. The scramjet bullets of the sabot pistols of Trillicon have built in cameras and some limited steering capabilities. Zetatech's Marksman Gun is equipped with a n expert system that can act as a point defence or drone if placed on a tripod or suitable vehicle (although the price tag deters most people).
