十陣概論
Overview of the Ten Formations
凡陣有十:有方陣,有圓陣,有疏陣,有數陣,有錐行之陣,有雁行之陣,有鉤行之陣,有玄襄之陣,有火陣,有水陣。此皆有所利。方陣者,所以也。圓陣者,所以也。疏陣者,所以也。數陣者,為不可掇。錐行之陣者,所以決絕也。雁行之陣者,所以接射也。鉤行之陣者,所以變質易慮也。玄襄之陣者,所以疑眾難故也。火陣者,所以拔也。水陣者,所以倀固也。
Formations number ten in all: the square formation, the circular formation, the sparse formation, the dense formation, the wedge formation, the goose formation, the hook formation, the mysterious-shield formation, the fire formation, and the water formation. Each has its particular advantage. The square formation is used for [lacuna]. The circular formation is used for [lacuna]. The sparse formation is used for [lacuna]. The dense formation is made so it cannot be disrupted. The wedge formation is used for decisive breakthrough. The goose formation is used for engaging with missile fire. The hook formation is used for changing dispositions and altering plans. The mysterious-shield formation is used for creating confusion and complicating the enemy's situation. The fire formation is used for seizure. The water formation is used for holding firm positions.
Notes
The ten formations represent a comprehensive tactical system. Some purposes have been lost due to damage to the bamboo strips (particularly for the square, circular, and sparse formations). The 'mysterious-shield formation' (玄襄之陣) is unique to this text and appears designed for psychological warfare — creating confusion about one's true dispositions.
