QUOTE : The same effort to conserve force was also evident in war, at the tactical level. The ideal Roman general was not a figure in the heroic style, leading his troops in a reckless charge to victory or death. He would rather advance in a slow and carefully prepared march, building supply roads behind him and fortified camps each night in order to avoid the unpredictable risks of rapid maneuver. He preferred to let the enemy retreat into fortified positions rather than accept the inevitable losses of open warfare, and he would wait to starve out the enemy in a prolonged siege rather than suffer great casualties in taking the fortifications by storm. Overcoming the spirit of a culture still infused with Greek martial ideals (that most reckless of men, Alexander the Great, was actually an object of worship in many Roman households), the great generals of Rome were noted for their extreme caution. It is precisely this aspect of Roman tactics (in addition to the heavy reliance on combat engineering) that explains the relentless quality of Roman armies on the move, as well as their peculiar resilience in adversity: the Romans won their victories slowly, but they were very hard to defeat. Just as the Romans had apparently no need of a Clausewitz to subject their military energies to the discipline of political goals, it seems that they had no need of modern analytical techniques either. Innocent of the science of systems analysis, the Romans nevertheless designed and built large and complex security systems that successfully integrated troop deployments, fixed defenses, road networks, and signaling links in a coherent whole.
