From " Weapon Systems of the Twenty First Century or the Upside-Down Evolution" by Stanislaw Lem (translated 1986):
Some of the pseudo-insects could pierce the human body like bullets; others could form optical systems to throw sunlight over wide areas, altering the temperature of large air masses so as to produce heavy rainfall or fair weather, according to the needs of the campaign. There existed "meteorological insects" corresponding to nothing we know today. The endothermic synsects, for example, absorbed large quantities of energy for the sole purpose of causing a sudden drop in temperature over a given area, resulting in a thick fog or the phenomenon known as an inversion. Then there were synsects able to concentrate themselves into a single-use laser beamer; they replaced the artillery of the previous century -- although one can hardly speak of replacement, since artillery as we understand it would have been of as much use on the battlefield as slings and catapults. New weapons dictated new conditions of combat and, therefore, new strategy and tactics, both totally unhuman.
For those who loved the uniform, the flag, the changing of the guard, standing at attention, drill, medals, and bayonet charges, the new era of war was an affront to their noble ideals, a mockery, a disgrace! The experts of the day called the new military science an "upside-down evolution," because in nature what came first were the simple, microscopic systems, which then changed over the eons into larger and larger life forms. In the military evolution of the postnuclear period, the exact opposite took place: microminiaturization.
The microarmies developed in two stages. In the first stage, the unhumaned microweapons were still designed and built by people. In the second stage, microsoldiers were designed, combat-tested, and sent to be mass-produced by "construction battalions" of nonliving microdesigners. A phenomenon known as "sociointegrative degeneration" displaced humans first from the military and later from the weapons industry. The individual soldier degenerated when he ceased to be an intelligent being with a large brain and grew increasingly small and therefore increasingly simple, or when he became disposable, a "single-use soldier." (Some of the antimilitarists had maintained, long before, that modern warfare's high mortality rate made "single-use soldiers" of all the combatants, with the exception of the top-ranking officers.) In the end, a microfighter had as much brain as an ant or a termite.
The strategical-numerical superiority of the computer-produced echelons finally forced even the most competent of commanders, including field marshals, into retirement. A tapestry of ribbons and medals on the chest was no protection against being put out to pasture. In various countries, at that time, a resistance movement developed among career officers. In the desperation of unemployment, they even joined the terrorist underground. It was a malicious trick of history -- no one deliberately planned it -- that these insurrections were crushed by means of micro-spies and minipolice built on the model of a particular cockroach.
This roach, first described in 1981 by an eminent American neuroentomologist, has at the end of its abdomen fine hairs that are sensitive to even the slightest stirring in the air. Connected to a special dorsal nerve bundle, the hairs enable the roach to detect the approach of an enemy, even in complete darkness, and so to flee instantly. The counterparts to these hairs were the electronic picosensors of the minipolicemen who concealed themselves in cracks in old wallpaper at the rebel headquarters.
