पृथग्वा सहयाने वा विश्वासेनातिसंहितम् ॥ कZ_०८.५.२४अब् ॥
pṛthag vā sahayāne vā viśvāsenātisaṃhitam
Whether acting separately or moving jointly, one should not be bound too tightly by trust (in the ally).
Maintain independent logistics and intelligence, keep command unity, limit information exposure, and ensure exit options even in joint operations.
