हस्तिनामुरस्यं रथानां कक्षावश्वानां पक्षाविति मध्यभेदी ॥ कZ_१०.५.३२ ॥
hastinām urasyaṃ rathānāṃ kakṣā aśvānāṃ pakṣāv iti madhyabhedī
Elephants form the breast (main front); chariots the ‘armpits’ (supporting shoulders); cavalry the wings—this is the madhyabhedī (center-breaking) formation.
A decisive rupture of the enemy center using a heavy shock-front, while wings provide mobility and exploitation.
