Which flares are characterized by the presence of a decal on their flanged end?

The presence of a decal on the flanged end is a distinctive characteristic of specific models of flares. In the context of the question, M211 and M212 flares are the correct models identified by this particular feature. The decal often indicates important information about the flare, such as its specifications, safety instructions, or usage guidelines, contributing to safety and operational understanding during deployment.

The M211, known for its application and reliability, shares the same decal feature with the M212, which is another model that also incorporates this design element. Understanding these characteristics can enhance the ability to identify and correctly utilize these flares in various situations. The ability to distinguish these models based on their features is valuable in ensuring that the right equipment is used in appropriate scenarios, particularly in emergency services and military operations.

Other options do not include those specific models that possess the decal feature, making them less relevant in this context. Thus, the identification of M211 and M212 as the correct answer reflects an understanding of the characteristics that define these particular flares in comparison to others.
