A suicide mission is a task which is so dangerous for the people involved that they are not expected to survive. The term is sometimes extended to include suicide attacks such as kamikaze and suicide bombings, where the people involved actively commit suicide during execution of the mission. The risks involved with suicide missions are not always apparent to those participating in them or to those who plan them. However, for an action to be considered a suicide mission someone involved must be aware of the risks. A mission that goes horribly wrong is not a suicide mission. An individual or group taking part in a mission may perceive the risks involved to be far greater than what they believe to be acceptable, while those planning or commanding the mission may think otherwise. These situations can often lead to refusals to participate in missions on the basis that they are "suicide missions". Similarly, planners or commanders may be well aware of the risks involved with missions while those participating in them may not.
