Four
U.S. Army units took part in the Operation Buster–Jangle "Dog" test for combat maneuvers after the detonation of a nuclear weapon took place. These units consisted of: • 1st Battalion 188th Airborne Infantry Regiment
11th Airborne Division • 3rd Medical Platoon 188th Airborne Medical Company • Platoon Company A
127th Engineer Battalion • Battery C 546th Field Artillery Battalion Personnel were instructed to create foxholes and construct gun emplacements and bunkers in a defensive position 11 km south of the detonation area. After the nuclear bomb was detonated, the troops were ordered to move forward towards the affected area. While traveling closer to ground zero, troops witnessed the nuclear weapon's effects on the fortifications that were placed in the location in preparation for the tests. The ground troops got as close as 900 meters from ground zero before they were instructed to move out of the area. The
Human Resources Research Office was tasked with gathering data on the psychological experiences of the troops after witnessing such a detonation and moving closer towards the affected area. | Minimum mass design,
fizzle (yield "less than a pound"); yet it yielded a lower bound on viable
plutonium mass. October 19 attempt failed due to control wiring problem. |- !
