So team Event 5 is a couplet of cleans and rope climbs, probably broken up into two groups of three men and three women and likely with heavy cleans. But notice the Glock and the bed of bullets he uses as the background for this announcement. Right on the heels of announcing the winners of the Games will be given Glocks, Castro sure knows how to fan the flames of internet comment sections.
