only certain colleges may compete after securing a bid in the previous season, and represents the best talent of college paintball and includes universities such as Drexel University, University of Maryland, Illinois State University, Purdue University, University of Connecticut, Penn State University and 10 other teams across three conferences all fighting for a national title. The association's 2007 playoff tournament was aired on Fox Sports Net's digital cable college sports network, Fox College Sports. Airsoft Airsoft is a competitive sport similar in concept to paintball, in which participants from opposing teams eliminate opponents by hitting each other with solid round plastic pellets launched from low-powered smoothbore air guns called airsoft guns. It is different to paintball in that airsoft pellets do not visibly mark the targets like paintballs, and thus the sport relies heavily on an honor system where a hit player has the ethical duty to call himself out of play, regardless of whether anyone else sees it happen. Most airsoft guns are also magazine-fed (unlike the commonly top-mounting pellet loader of paintball markers) with mounting platforms compatible with real firearm accessories, and tend to more closely resemble real guns in appearance, making them more popular for military simulation and historical reenactments. The greater toughness of airsoft pellets also allows the use of better powerplants and apparatus such as hop-up device for improved external ballistics, making the gameplay more accurately resemble real gunfights. They are also much cheaper for casual players to participate than paintball. Airsoft gameplay varies in style and composition just like paintball and is played in both indoor and outdoor courses. Situations on the field frequently involve the use of real-life military tactics to achieve objectives, and it is not uncommon for participants to emulate the uniforms and equipment of real military and police organizations for a sense of realism. Games are normally supervised (and sometimes umpired) by trained on-site administrators, and players' airsoft guns are usually checked through a chronograph to enforce power output restrictions. There are currently no formal national or international governing bodies for the airsoft sport. Competitive tournaments are usually organized by private clubs or among enthusiasts and professional/semi-professional teams (often referred to as "clans"), with rules and restrictions varying from event to event.
