OT-WWI AEF USMC Marine Service Numbers

4th Brigade WWI AEF Marine Service Numbers have nothing to do with time in service or the date you joined.:madsmile: If you give me an AEF WWI Marine Service Number, I can tell you what Regiment and Battalion he was in (and maybe Company), or if he was a replacement.:thup:

I caught on when I saw numerous Battalion Scout Snipers with consecutive Serial Numbers without regard to their Enlistment date.:clap:

The Marines were smarter than I thought.:bow: If a Marine found another wounded Marine, he would know exactly to what unit the wounded Marine belonged.:crying:
