Justin Brown- President
Literally growing up with Paintball, Justin's father Forest Brown, opened one of the first Paintball fields in the country, Challenge Park, in 1985 just outside of Chicago.

Working at the family business, Justin saw Paintball go through many changes and spent his weekends refereeing, running events, working at their retail stores, building forts, trench systems, trails and cleaning the rental equipment. Lots of rental equipment.

After high school, Justin travelled and lived throughout the west, and started a family, but always keep up on Paintball and its trends, running events where he lived and playing when he could.

In 1999, his father asked him to return to Chicago to help him build and operate his newest venture. Forest had secured a deal with a major Paintball manufacturer to build the most original and elaborate Paintball field in the world. In addition, it would also be the Worlds First Extreme Sports Theme Park, Challenge Park Xtreme, and feature a skatepark, bmx race track, mountain biking trails and more. During construction, Justin managed crews building fields, trails and other infrastructure for the park, and also oversaw the other construction project managers.

After the park opened in 2000, Justin became the Operations Manager and was in charge of running the day to day operations, referees, and was given the task of bringing exciting events to the new facility. Justin began right away by bringing in some cool events such as the William Shatner celebrity Paintball game, a tour stop by the Tony Hawk Gigantic Skate Tour to chill out and play Paintball between shows, the Crazy Freakin Bikers, (CFB) Mat Hoffman's BMX X-Games Qualifier competition, rock concerts, scenario games, bmx exhibitions and more.

In 2002, Justin finally got to see something he had heard a lot about, but hadn't seen yet. Airsoft. The Minnesota Airsoft Association, led by Matt Brown (no relation), and Gabe Stitzel brought about 25 players and their equipment to the park to showcase it to Justin and Forest, and they were immediatley hooked. Justin saw the potential of Airsoft as a great sport and immediatley began to organize Airsoft games for the park in 2003.

In the Spring of 2003, after a disagreement with the manufacturer/partner that bankrolled the construction of the park over business philosophies, safety and Airsoft, Justin's fathers' contract was cancelled. Justin was asked to stay, but you can imagine what he said after his father had basically been fired, without whom the park wouldn't even exist.

Not one to waste time, Justin opened a retail store in Joliet, Illinois specializing in Paintball and Airsoft supplies in August of 2003 and began running his Airsoft events shortly thereafter.

Using his knowledge of event running, promotion and planning, Justin quickly became the premier Airsoft event organizer in the Midwest, making his mark with the popular CODENAME: Thunder series of events. Using his film production company, Summit Lake Entertainment (which we haven't mentioned yet), Justin produced the extremely popular CODENAME: Thunder DVD, one of the highest selling Airsoft DVDs of all time.

Wanting to focus more on his budding film career and event organizing, Justin sold the majority of his share in the Joliet retail store and began the adventure known as Combat Sport
