Which bomb support rollers may be used with roller extensions?

The correct answer, which states that all rollers may be used with roller extensions, indicates that both the material composition and design of the rollers allow compatibility with roller extensions. This means that regardless of whether the rollers are made of aluminum, steel, or composite materials, they can effectively function with roller extensions during loading and unloading of munitions, enhancing the operational flexibility and efficiency in handling various types of bombs.

This versatility is critical in munitions operations because it ensures that the systems in use can accommodate different kinds of equipment without limiting the ability to support multiple tasks. Such compatibility is essential for safety and efficiency in environments where timely handling and deployment of munitions is necessary.

When examining the other options, it's clear that restricting the use to only one type of roller material would limit operational capability and flexibility in different scenarios, which is contrary to the multifunctional purpose these support rollers serve. Therefore, understanding that all variations of rollers can be utilized with extensions illustrates the importance of adaptability in munitions systems operations.
