mārgādeśikam parabhūmiyogyam ariyuddha-pratilomam aṭavī-bala-prāyaḥ śatrur vā bilvaṃ bilvena hanyatām; alpaḥ prasāro hantavyaḥ ity aṭavī-bala-kālaḥ |
When the enemy is chiefly a forest/tribal force—one that knows routes, is fit for operating in another’s territory, and fights by irregular methods—he should be countered with his own kind (“a bilva is struck with a bilva”): engage him with limited, controlled operations and eliminate him with restricted maneuver. This is the situation for employing forest forces.
Match the adversary’s force-type and tactics: use similarly adapted troops and methods rather than conventional formations that the terrain and enemy style will negate.
Against mobile raiders in difficult terrain, overextension invites ambush and supply failure; Kautilya recommends tight control of movement and objectives.
