Which of the following fuze setters can be used on 105mm rounds?

The correct response indicates that the IFS (Improved Fuze Setter) is compatible with 105mm rounds. This fuze setter is designed to adjust and set the various fuze parameters specifically for artillery shells, including those in the 105mm caliber range.

The IFS is recognized for its versatility and enhanced operational capabilities, allowing for faster and more precise fuze settings that adapt to different mission requirements. This makes it an essential tool for ensuring the effective use of artillery, contributing to both accuracy and safety.

In contrast, the other fuze setters listed, such as the M17, M2, and M23, are designed for different calibers or are outdated compared to the capabilities that the IFS offers for use with 105mm rounds. This distinction makes the IFS the appropriate choice among the options for setting fuzes on this specific caliber of ammunition.
