Being able to specify between medical emergencies and normal game stoppages tends to help response rate to medical emergencies.



It's only common knowledge so long as it's commonly taught.
I make sure it's part of the briefing at every game I go to. But you know how some children (airsofters) are. Either not paying attention or can't understand basic english.
Some of us (infrequently) still get shot at during a no duff. And it's always under such dumb conditions as being shot as a dead player:
"That guy is moving around with his gun down in a very non threatening manner! shoot him!"

Probably whistle blasts for a bigger field where a voice yelling no duff may not carry.
