Which three items must be on a Soldier when working in and around rotary wing aircraft?

In the context of working in and around rotary wing aircraft, the essential items required for a Soldier are critical for ensuring safety and identification. The presence of an ID card is essential for identification and access to secure areas, reflecting the chain of command and responsibility. Ear plugs provide necessary hearing protection due to the high noise levels associated with rotary wing aircraft, which can lead to hearing loss without proper protective gear. ID tags serve as a vital component of personal identification, especially in emergency situations, ensuring that Soldiers can be easily identified and documented.

In scenarios involving aircraft operations, these items collectively help enhance safety protocols and facilitate efficient identification of personnel, allowing for a more secure environment in high-risk areas around aviation operations. Other options may include useful items, but they do not comprehensively cover the necessity of identification and hearing protection consistent with the protocols for working near rotary wing aircraft.
