Orbital weapons are militarized satellites, capable of attacking targets on land or sea or in air or space. Perhaps the most formidable development in modern warfare, they push the advantage of high ground to the extreme and almost totaly exclude the possibility of counter-attack. Modern orbital emplacements shifted the global balance of power heavily in favor of the Roman Imperium, who has the sole right as a state to launch weapons satellites, allowing their armed forces to easily out compete the Mongols, Maya or Japanese. No present military has the means to defend against such weaponry.
