From the introduction: In battle, every advantage that a combatant can seize increases the likelihood that they can snatch victory from the jaws of defeat without severely injuring themselves in the process. To this end, one of the most effective ways that an individual can hamper their enemy is by making strategic attacks against specific regions of their adversaries’ bodies, hobbling them just enough that they can ultimately be felled. Such strategy allows combatants to hinder their enemies, making it easier to ultimately defeat them.
