Defending the Blue Line is a 501 (c)(3) non profit organization created by soldiers with the spirit of keeping hockey alive for the children of our nation's military heroes. Our mission at Defending The Blue Line (DTBL) is ensuring that children of military members are afforded every opportunity to participate in the game of hockey. We accomplish this by providing free equipment for military kids, hockey camps, special events, and financial assistance for registration fees and other costs associated with hockey.
