I have seen some of these before. These guys dig "artifacts", alot of times they run across caved in earthen bunkers and fighting positions. Quite possibly caved in entombments from artillery fire? I understand that all of the war dead they recover, have every attempt made at ID'ing, turned over to the authorities and given a proper buriel with military honors. There are some who would view this as grave robbing i suppose. I'll not make any judgments either way. There are still plenty of "surface" finds to be made, we found a few in Germany and Italy in the mid 70's when I was stationed there.
