पार्श्वस्थायी हि यातव्याभिसारो मूलाबाधकश्च भवति मूलाबाधक एव पश्चात्स्थायी ॥ कZ_०७.१३.२३ ॥
pārśvasthāyī hi yātavyābhisāro mūlābādhakaś ca bhavati mūlābādhaka eva paścātsthāyī
侧翼之势力(pārśvasthāyī)是既能进军攻向拟攻目标(yātavya),又能打击根基/本部(mūla)者;而打击根基者,在实质上就是后方之行动者(paścātsthāyī)。
The flank actor can both join operations against the target and threaten the core; whoever threatens the core functions as the rear threat in strategic terms.
