Paintball fails to meet even the first requirement to be a recognised sport as mandated by the olympics.
To make it onto the Olympic programme, a sport first has to be recognised: it must be administered by an International Federation which ensures that the sport's activities follow the Olympic Charter. If it is widely practised around the world and meets a number of criteria established by the IOC session, a recognised sport may be added to the Olympic programme on the recommendation of the IOC's Olympic Programme Commission
International Federations are responsible for one sport (or a group of similar sport disciplines, such as aquatics or skiing). They create a common set of rules and organise international competitions. The promotion of the sport is also a task of an international federation. Trusts are organizations or groups that have control over money that will be used to help someone else, such as the Youth Sport Trust. National Federations have the same objectives as an international federation, but within the scope of one country, or even part of a country, as the name implies. They support local clubs and are often responsible for national teams.
