At some point maybe marshalls will have to wear protective gear like a baseball helmet with the grill guard on the front or a football helmet.
One of my team guys got koed by a runaway mugen truggy and had a 17 stitch laceration on his forehead and another 5 stitch laceration on the bridge of his nose. Of course the bruising looked like he was in a UFC match....
I am just glad he is fine now, but it has concerned me personally over the years.
