"Gundoh Bugei" is a militant combat style that teaches efficiency in the use of gun tactics. Developed through analysis of thousands of recorded gun fights, it was determined that the geometric distribution of antagonists in any gun battle is a statistically predictable element. A trained warrior of "Gundoh" treats the gun as a total weapon. Each new position representing a maximum kill zone, inflicting maximum damage on the maximum number of opponents, while keeping the defendant clear of the statistically traditional trajectories of return fire.
The focus of "Gundoh Bugei" is style, and the usage of firearms in ways that they were not designed to be used. Shooting a gun from each hand, shots from behind the back, as well as the use of guns as melee weapons are all common. Pistols and submachine guns are frequently utilized by the opponents due to the light weight they provide, enabling their wielders to move more quickly. They are frequently held akimbo. The heroes are extremely agile and implement rolls, dives, slides, and falls while they duel, making for a graceful, ballet-like performance in the midst of gunfire.
One author who came upon a school of "Gundoh Bugei" wrote:
The more part of these warriors when they are seven years of age are sent to schools where they are taught many tricks of nimbleness and dexterity; there they teach them to dance and turn about and to twist on the ground, to take royal leaps, and other leaps, and this they learn twice a day as long as they are children, and they become so loose-jointed and supple that they make them turn their bodies contrary to nature; and when they are fully accomplished in this, they teach them to play with the weapon to which they are most inclined, some with bows and arrows, some with poles to become spearmen, but most with swords and bucklers, which is most used among them, and in this fencing they are ever practicing.
For many governments, the training of persons in the ways of "Gundoh Bugei" is a criminal offense. Persons caught with writings and/ or equipment related to the martial art can be subject to criminal fines and time in prison. In some regimes, masters of the martial art are considered "seditious rebels" and are considered "enemies of the state".
