Diagram of the Two-Wing Formation for the Deployment of Miscellaneous Forces

This diagram illustrates the "Two-Wing Formation" (二翼陣 — èryì zhèn) used by military forces (雜兵家 — zábīngjiā) when setting out on a campaign. The "Two Wings" refer to the flanking columns that can envelop an enemy or protect the main body of the army during an advance.

original: 前騎 — qiánqí; These are the leading scouts or light horsemen positioned at the head of each "wing" to screen the army's movement.

original: 前敵 — qiándí; This indicates the primary zone of engagement where the vanguard meets the opposing force.

original: 後衝 — hòuchōng; These are the heavy units or reserves positioned at the back, ready to "charge" through or provide a decisive impact once the enemy is engaged by the front lines.

The visual layout of this formation in the original manuscript shows two vertical columns of flags, creating a central corridor. This suggests a mobile formation used during a march or a flanking maneuver designed to wrap around an opponent's center.
