Elements for which a sequence has already been generated and are unique in the AFDIL population database also undergo haplogroup testing.
AFDIL has an FRS on file for 86% of all of the unaccounted-for from the Battle of Tarawa, but only 69% of these are mitochondrial references.
The AFDIL helped identify the remains of Tsar Nicholas II of Russia, who was assassinated and buried in 1918.
The AFDIL is collecting mtDNA samples from MIA family members to help the identification process.
For more information about providing a mtDNA sample to the AFDIL, maternal relatives of MIAs are asked to contact the USAF Missing Persons Branch 800-531-5501; Department of the Army 800-892-2490; Headquarters U.S.
AFDIL has used these stored DNA samples to identify casualties in Afghanistan as well as the uniformed victims of the Sept.

DNA sampling began in June 2015, and samples were sent to AFDIL on Dover Air Force Base, Delaware, where analyses began immediately.
By April 2016 nearly 5,000 DNA samples had been taken and submitted to AFDIL for mtDNA sequencing.
Once the elements are sampled, the samples are sent to AFDIL for the first round of sequencing, which targets mtDNA hyper-variable regions 1 and 2 (HVR1, HVR2).
Based on the composition of the loss population and the commingled assemblage and similarities in means and standard deviations, postcranial samples were prioritized in four tiers, representing 32.6% of the total samples submitted to AFDIL (Table 2).
The completion of the postcranial priority tiers took approximately 18 months, though it should be noted that during this time AFDIL also processed many other cases and projects as well as additional nuclear testing for the Oklahoma project.
