The World Series of S.W.A.T.
OSWCS competitions are unlike other SWAT competitions in that all are composed of live-fire, head-to-head events, conducted in full tactical gear, and only one round is provided per target, per man. The Canadian Tactical Challenge, The Rocky Mountain Tactical Challenge and the Northeast SWAT Challenge are open competitions. Any law enforcement (sworn officers) SWAT or special operations team may participate as long as all members are from the same department. All Star and composite teams are not permitted.
