From left, Airmen Christopher Zamarron, Tony Mainer and Brendan Adame, 364th Training Squadron cable and antenna systems apprentice course students, participate in a ground based tower rescue at Sheppard Air Force Base, Texas, Oct. 23, 2018. Adame and Zamarron are playing the roles of rescuers while Mainer is the victim. Several situations like equipment failure or injury could leave the climber unable to descend the tower on their own. At this point, a team would be sent up to hook up the victim while a ground team waits below ready to lower them. (U.S. Air Force photo by Airman 1st Class Pedro Tenorio)
