The Japanese player may perform one kamikaze attack per turn on a target of their choosing at no additional cost. Fighters, zeros, and light bombers are the only units allowed for a kamikaze attack.
The unit used for the attack may use up all its movement to reach its intended target, and receives one combat roll. The Japanese player would chose the target, and make an attack roll scoring hits on a of 4 or less (D6), 8 or less (D12), or 13 or less (D20). The unit used for the kamikaze is removed from play regardless if the attack was successful or not.
This attack is a pre-combat attack meaning anti-aircraft guns and naval bases would not receive first strike rolls against the kamikaze unit. Also, units hit by kamikazes would not receive defensive rolls. Kamikaze hits scored on capitol ships would only damage the unit.
