The US Army to Give Medal of Heroism to JROTC Cadets Killed in Florida Shooting The three students, 14-year-old Alaina Petty, 15-year-old Peter Wang and 14-year-old Martin Duque, were killed while working to help their classmates escape the shooter. The Medal of Heroism is one of the highest honors awarded to Junior Reserve Officers' Training Corps cadets. The achievement must be an accomplishment so exceptional and outstanding that it clearly sets the individual apart from fellow students or from other persons in similar circumstances. The performance must have involved the acceptance of danger and extraordinary responsibilities, exemplifying praiseworthy fortitude and courage. The families of the children will receive the medals at their respective memorial services.
