Zsinj's doctrine was a military tactic conceived by Warlord Zsinj that stated if the enemy chooses the battlefield, they have more resources available to them than what meets the eye, and therefore the battlefield must be changed to one the enemy can't have prepared. Zsinj implemented this doctrine even in situations where he initially appeared to outnumber or outgun the enemy. Zsinj's doctrine caused the warlord to flee from Solo Fleet during the Battle of Vahaba.
