What is the correct term for the small two-way radios individual firefighters can carry, once called walkie-talkies?

Portable radios are the correct term for the small two-way radios that firefighters can carry. These devices allow for effective communication among team members during operations, which is critical for safety and coordination on the fireground. Portable radios are designed to be lightweight and compact, enabling firefighters to easily carry them during their work.

The term "walkie-talkie" is often associated with basic two-way radios, but in the firefighting context, portable radios are specialized equipment that can withstand harsh conditions, including exposure to heat and moisture. These devices are typically equipped with features such as channel options, emergency signal capabilities, and sometimes even built-in noise cancellation to facilitate clear communication in noisy environments.

While mobile radios refer to larger radios installed in vehicles and can provide coverage over larger areas, they are not portable. Field packs are not specifically a term used to describe communication devices, and PASS (Personal Alert Safety System) devices serve a different purpose, designed to alert firefighters if they are down or not moving for a certain period, thereby enhancing safety on the scene.
