The neckbeards have 50 1oz hollowpoint slugs and 50 rounds of ten pellet 0000 buckshot.
The romans are armed with body armor, shields and short swords along with some spears.
The neckbeards have a 7x7 meter 3 story bamboo castle in the middle of a Wal-Mart parking lot that the Romans are trying to take by force.
10 vs 100 and you may have fight but even then the parking lot is too far to run across. The castle is is just giving the handicap to the wrong side.
