पुरस्तादध्याघाते मकरेण यायात्पश्चाच्छकटेन पार्श्वयोर्वज्रेण समन्ततः सर्वतोभद्रेण एकायने सूच्या ॥ कZ_१०.२.०९ ॥
purastād adhyāghāte makareṇa yāyāt paścāc chakaṭena pārśvayor vajreṇa samantataḥ sarvatobhadreṇa ekāyane sūcyā
When expecting a frontal strike, advance in the ‘makara’ array; when threatened from the rear, use the ‘chakaṭa’ (cart) array; when threatened on the flanks, use the ‘vajra’ (diamond/thunderbolt) array; when threatened on all sides, use the ‘sarvatobhadra’ (all-round) array; on a single narrow track, use the ‘sūcī’ (needle) array.
Formation is selected by the direction of threat and the constraint of terrain/route—deploy to cover the most likely attack axis.
A narrow track prevents broad deployment; a needle-like column preserves movement while maintaining controllable order.
