BBs do not break up or leave coloured marks so an honour system is used to register hits. Players raise their hands and call out “hit” to indicate that they have been shot (a team of marshals will be on site at all times to uphold our standards of fair play). Being hit by a BB fired from an Airsoft gun can be comparable to being flicked or pinched very hard, and if you are hit on a thinly covered area you will definitely notice it. However, it doesn’t leave permanent marks and there is no lasting pain past the initial sting.
