Upāya-dharma and Senāyoga: Expedient Ethics & Army Deployment
संहतान् योधयेदल्पान् काम॑ विस्तारयेद् बहुन् । सूचीमुखमनीकं स्यादल्पानां बहुभि: सह
saṁhatān yodhayed alpān kāmaṁ vistārayed bahūn | sūcīmukham anīkaṁ syād alpānāṁ bahubhiḥ saha ||
Bhishma said: When one has only a small force, one should command them to fight in a tight, unified formation; but when one has many warriors, one may spread them out as desired over a wide front. And when a small force must contend against many, the battle-array called the “Needle-point” (Sūcīmukha) is considered suitable—concentrating strength into a piercing tip rather than dispersing it.
भीष्म उवाच
Bhishma teaches adaptive leadership in warfare: concentrate a small force into a cohesive, disciplined mass, but deploy a large force with breadth and flexibility. When outnumbered, use a formation like Sūcīmukha that focuses power into a penetrating point, minimizing the disadvantages of being few.
In the Shanti Parva’s instruction on rājadharma, Bhishma advises the king on practical conduct of war and army deployment. Here he gives a rule-of-thumb for arranging troops based on relative numbers and recommends the Sūcīmukha formation when a smaller contingent must face a larger one.
