Yep, but unless some real harm is done, dropping guns, spitting out dummies, or stopping play mid game over a handful of stray bbs isn't gonna happen.
Sure, find a Marshall & report what is perceived to be a problem, & there's 3 likely outcomes:
1. He'll chuckle & tell you that it's fast moving warfare, & shit happens.
2. He'll make an announcement before the next game, but it will warn everybody, dead men included, to be more switched on.
Or 3. He'll tell you to grow a pair.
Sites will favour the many over the few, financially it makes sense, even if it's morally wrong, that's why so many site have home team regulars that are impervious to hits, mag restrictions, or even chronos, money talks.
