The Yari Ashigaru is just a collection of poorly armed and thinly protected peasant warriors. They will usually run from battle when confronted by a superior enemy. The Yari Ashigaru should be positioned along the flanks, out of harm's way, or stationed towards the rear to protect ranged combat units.
In scenarios where the only objective is to take out enemy leaders, the objective can be completed by flooding the enemy's home territory with dozens of untrained ninjas then ordering them all to attack the enemy Daimyo. They will have about a 10% chance of success.
