Army in the Zhou Dynasty also used the number “5” as their basic units. Every five infantries make up a combat team. Their weapons also have 5 kinds such as bow, pike, lance, dagger and halberd. The cooperation of these 5 kinds of weapons can greatly improve their combat effectiveness and help them become invincible.
Tips:As early as in the Zhou Dynasty, “5” was already the unit for army. The army of the Zhou Dynasty was “five soldiers are Wu, five Wu are Liang, four Liang are pawn, five pawns are brigade, five brigades are division, and five divisions are army.” So there were about twelve thousand and five hundred soldiers in one army.
