The 303rd Wildcards are a Colorado Based Airsoft Team. Their primary goal is to train members to be prepared to attend National Level Events (Operations) both inside and outside of Colorado. They are focused Military Simulation (MilSim) styled events and primarily attend events hosted by the Colorado Milsim, LionClaws, and Milsim Event (Frosty and Claymore) organizations.

The 303rd Wildcards was created in the fall of 2008 by a group of players from Airsoft Colorado that wanted to make attending Milsim events a priority. They created their training regimen with an emphasis on preparing players for the rigors of those games, and giving them the skill base to not just attend an event, but to excel and demonstrate the determination that makes Colorado players famous.
