Here's a situation from the game involving movement towards a "Cove": I position a unit with 1 attack against the last stack of neutral units, and the unit, the jerk, ignores the 1 attack and runs towards a stack of level 1 units that can only reach it on the next turn. I haven't seen anyone do this before. It happened in a battle against centaurs, and they were running towards a stack of imps.
Sometimes, they also ignore an entire stack, as I understand it, which they cannot kill (even one unit from the stack), and they die immediately from the counterattack.
