Which three actions must be taken immediately after an ammunition malfunction occurs at a live firing range?

The correct answer involves three critical actions that ensure safety and proper procedure following an ammunition malfunction during live firing.

Ceasing fire is the immediate action required to prevent any further danger or complications, as continuing to fire could exacerbate the situation or lead to additional malfunctions. Following this, notifying range control is essential as they oversee the operation of the range and are responsible for maintaining overall safety and coordinating emergency response if necessary. Securing the malfunction site is crucial to prevent unauthorized access and to allow qualified personnel to assess the situation safely without interference.

These actions prioritize the safety of all personnel on the range and ensure that the malfunction is handled according to established protocols, contributing to a systematic resolution of the incident. The focus is on immediate actions that not only address the malfunction but also safeguard those present and maintain control over the situation. In contrast, the other options either include actions that are not as immediate or do not directly address the immediate danger posed by the malfunction.
