पत्त्यश्वरथद्विपानां सारत्रिभागमुरस्यं स्थापयेत्द्वौ त्रिभागौ कक्षं पक्षं चोभयतः अनुलोममनुसारम् प्रतिलोमं तृतीयसारम् फल्गु प्रतिलोमम् ॥ कZ_१०.५.४३ ॥

Of infantry, cavalry, chariots, and elephants, station the best third (sāra) in the front; place the remaining two-thirds on both sides as the flanks and wings. Arrange the follow-up (anusāra) in direct order; place the third-grade core behind/in reverse order; and position the light (phalgu) contingent in reverse order.
Maximize shock and cohesion at first contact while insulating weaker elements from immediate collapse; keep depth and controlled withdrawal/rotation options.
