Ranger School is designed to physically stress students to a point short of death. Deaths have occurred during Ranger Training. In the winter of 1977, two students in class 2-77 died of hypothermia while on patrol in the Florida swamp. In 1985, in the Florida phase, a soldier drowned crossing a stream against a strong current. In March 1992, a student with sickle cell trait died after exposure to high altitude and stress in the mountain phase. The Ranger Training Brigade did not know about his medical issue until after his death. In March 1992, a Ranger student died from a fall on the Slide for Life. The "worst incident in the 44-year history of the school" occurred on 15 February 1995 during the Florida Phase of class 3–95. Captain Milton Palmer, 2LT Spencer Dodge, 2LT Curt Sansoucie, and SGT Norman Tillman died from hypothermia. Investigations of the incident were conducted by the U.S. Air Force, the Ranger Training Brigade, and the U.S. Army's Safety Board. The results were determined to be a result of a combination of human errors exacerbated by "unexpected weather conditions". Nine Ranger Instructors were disciplined and the 6th Ranger Training Battalion commander was relieved. As there was no basis for criminal charges, none were court-martialed. The four dead Ranger School students were posthumously awarded the Ranger Tab. As a result of the 1995 deaths, 38 new safety measures were implemented in the Florida Phase. According to John Lock,
