सारबलमग्रतः कृत्वा कोटीष्वनुसारं कुर्यात्जघने तृतियियसारं मध्ये फल्गुबलम् ॥ कZ_१०.५.४६ ॥
sārabalam agrataḥ kṛtvā koṭīṣv anusāraṃ kuryāt jaghane tṛtīyiyasāraṃ madhye phalgubalam
Having placed the core (sāra) force in front, he should arrange supporting echelons (anusāra) on the wings; put the third-grade core at the rear, and the light (phalgu) force in the middle.
10.5.45 stresses phalgu at the extremities for maneuver; 10.5.46 presents an alternative scheme placing phalgu in the middle while supports occupy the wings—both are conditional templates within the same doctrine of graded deployment.
