पितृपुत्रभ्रातृकाणामायुधीयानामध्वजं मुण्डानीकं राजस्थानम् ॥ कZ_१०.३.३९ ॥
pitṛputrabhrātṛkāṇām āyudhīyānām adhvajaṃ muṇḍānīkaṃ rājasthānam
(Let there be units) of fathers–sons–brothers among the fighting men—without separate banners, with close-cropped/identifiable ranks—and stationed around the king’s position (as the royal guard/center).
Kinship increases mutual monitoring and commitment, lowering desertion and raising willingness to hold position—especially critical around the king.
