पत्तयः पक्षयोरश्वाः पार्श्वयोः हस्तिनः पृष्ठतो रथाः पुरस्तात्परव्यूहवशेन वा विपर्यासः ॥ कZ_१०.५.३८ ॥
pattayaḥ pakṣayor aśvāḥ pārśvayoḥ hastinaḥ pṛṣṭhato rathāḥ purastāt paravyūhavaśena vā viparyāsaḥ
Place infantry on the wings, cavalry on the flanks, elephants to the sides, and chariots at the rear (or in front); or reverse the arrangement as required by the enemy’s formation.
Doctrine is conditional: the commander should reconfigure force placement based on the opponent’s array rather than follow a fixed template.
