What type of ammunition is typically used in a Temporary Impact Area?

The correct answer is that non-dud producing ammunition and explosives are typically used in a Temporary Impact Area. This type of ammunition is specifically designed to minimize the risk of producing duds, or unexploded ordnance, which can pose safety hazards to personnel after the exercise has concluded.

Using non-dud producing ammunition ensures that any rounds that do not detonate will not remain as potential threats in the training area, thus maintaining safety for future operations and for personnel who may enter the area later. This practice aligns with safety protocols aimed at preventing accidents and ensuring a secure training environment.

Dud-producing ammunition would not be used as it increases the risks associated with future access to the area. Inert rounds, while safe, are not ideal for training in a realistic environment that prepares Marines for the type of conditions they might face. Standard live rounds carry the risks associated with duds and are typically reserved for different types of training or operations where safety measures can be thoroughly managed.
