Marine Corps Range Safety Officer (RSO) Practice Test

The situation described indicates that Range Control has prohibited maneuvering in a specific area during a MK-19 firing exercise, which suggests a high level of risk associated with operations in that zone. The correct answer identifies this area as a high-hazard impact zone.

In military training and operations, areas designated as high-hazard are those where the potential for injury or damage is significant due to the activities being conducted, especially with the use of weapons systems such as a MK-19, which is an automatic grenade launcher known for its explosive projectiles. The restriction on maneuvering indicates that there are serious safety concerns that necessitate avoiding personnel movement to mitigate the risk of accidents or injuries from stray rounds or debris.

Controlled impact areas, while also potentially hazardous, imply a level of management and oversight that allows for some activities to continue under specific parameters. Safe-hazard areas typically allow for unrestricted access due to low risk, and low-hazard areas suggest minimal danger from nearby operations. The designation of high-hazard serves as a clear warning that strict controls must be observed to protect personnel and equipment.
