KIA: An individual who is killed in action, whether at the front or by enemy action in the rear areas, or if a prisoner of war, whether by air bombardment of his prison camp or by being shot while escaping is designated KIA--Killed in Action.
FOD:Individuals who are determined to be dead under Public Law 490 are designated FOD--Finding of Death.
Mickey--The above citations are from the Honor Roll of War Dead, Forward Page.The course of events would be as follows. 1: A person is shot down in an aircraft and no trace of him can be located as dead, prisoner of war,or in any form.He is declared MISSING.
2: A person is maintained in the MISSING category for a-year-and-a-day which allows Service Components to determine what became of the individual either through interviewing crew mates who had been prisoners or otherwise recovered, finding the wreckage with the individual in it, or some other evidence that he had died in the crash, shoot down or by other means. If no determination is made after the year-and-a-day the person is "presumed dead" under provisions of Public Law 409 which is the FOD.What this effectively does is start the Government paperwork moving whereby the family is compensated for the loss via GI Insurance, and/or other benefits due and owed.It also allows for some substantive data to be recorded for memorialization as we see so many times on this board.
If after the FOD, information is uncovered as to the terminal status of the individual, then he is changed to KIA.
IDPFs are an ongoing record of events drawn from numerous sources, so one can not read them as a pure logical/sequential chain of events.
