The 7th Division relieved the Marines at Belleau Woods and got slaughtered. They had zero combat experience when Harbord threw them into a bee hive. Harbord's incompetance was rewarded with a promotion instead of a firing squad.
Those are some of the designated snipers of the Battalion. They are probably being shown with their respective Company. I have seen no pictures of any Intelligence Section, probably due to the fact that snipers were not so highly thought of in WWI. In all Muster Rolls, Intelligence Section men were carried on their respective Company rolls with no indication of their true jobs.
