Conducting an Airborne operation is an inherently high risk mission. When water, wire, or tree hazards are on or in close proximity to the intended drop zone, the probability and severity of injuries is increased, the possibility of fatalities during airborne operations is also present.This appendix provides planning considerations for water, wire, and tree emergency landings. It also aids the commander in conducting drop zone deliberate risk assessments and analysis, and provides the commander, DZSO or DZSTL, and JM personnel with operational and logistical planning control measures to assist in mitigating the inherent risks jumpers might encounter during Airborne operations.Individual service components may modify these requirements based on the availability of training aids and equipment. They will also follow their service risk assessment procedures and regulations.
