The Americans were running a parallel graves and missing research programme over much of the same territory as the British. They carried out similar procedures, but performed an additional, highly extensive series of duties because bereaved relatives were offered the choice of having their dead repatriated. (No repatriation in any circumstances was permitted for the British dead.)
The two American services which carried out the care of the American dead were the Graves Registration Service and its successor the American Graves Registration Service. Both organisations wrote an account of their work, but whilst that of the Graves Registration Service is short and to the point, that of the American Graves Registration Service, published in 1957, is 700 pages long and immensely detailed.*
The Americans made both an art and a science out of their burial and identification procedures, which formed a strong contrast to the frequently ad hoc arrangements of the British.
