Final answer:
An adversary using IW methods typically employs deception, strategic planning, and psychological manipulation to impose his own will on the enemy while preventing the imposition of the enemy's will.
Step-by-step explanation:
An adversary using IW (Irregular Warfare) methods typically employs strategies that are meant to outsmart the enemy by manipulating their perceptions and exploiting their weaknesses. The principles mentioned suggest that the clever combatant will find ways to impose his will on the enemy while preventing the enemy's will from being imposed on him. This includes offering advantages to bait the enemy, inflicting damage to keep them at bay, and employing deception to hide the true state of one's capabilities and intentions.
More distinctly, the adversary may utilize deception like appearing weak when strong or being near when perceived to be far, to entice the enemy into a trap (LibreTexts™). They may also use a strategy known as a straw man, where a weaker version of the enemy's position is presented to be easily defeated. This is part of a greater scheme of calculating all possible outcomes and advantages, thereby leading to victory through intelligence and strategic planning.
