The so-called Guided Aim Technology was one of the earliest 'innovations' introduced by Professor Ves Larkinson.
These days, only the immigrants of the Komodo Star Sector and the determined enemies of the Larkinson Clan were aware of this powerful capability.
The Larkinsons themselves did not really go out of their way to advertise the unnaturally high hit rates of their Transcendent Punishers. There was no reason for them to give their enemies greater convenience and give them the opportunity to figure out countermeasures in advance.
The public largely remained in the dark about the existence of this particular capability.
It did not help that Ylvaine's guidance had long been reserved as an exclusive benefit to loyal worshipers of the Great Prophet.
During the Sand War, many different parties including the Mech Trade Association attempted to reverse engineer the Holy Soldier mech model in order to 'steal' this extraordinary capability.
