The Roman Legions in the time of Nero. They numbered 28 and each contained about 5000 fighting men. They wore leather armor and carried wooden shields, and fought with 50 cm short swords. So about 140,000 bronzeage warriors, subject to the diseases that plagued large armies at the time. -Versus- The entire population of Narutoforums (30k maybe?), transported back into, say, the city of Ostia. We are immune to most of the diseases of the time or if not immune, having a much higher resistance. All modern knowledge and devices carried on our persons (cellphones, pens, money, ID cards) at the time can be used. Perhaps Utahcrip will have a gun or two on him. We have a handful of members with knowledge about modern medicine, metallurgy, electronics, chemestry, and probably the greatest collection of anime trivialists in the history of the world. (Nybarius, KnK, Martryn come to mind as intellectual assets) Also, the historians know all about the Romans, they know nothing about us. However the population of NF is comprised in large part of women, small children, and men in poor condition to fight. NF gets 3 months prep time while the Legions assemble. Who gets wiped out?
