Which flares have a decal located on the flanged end?

The correct answer identifies the specific types of flares that feature a decal on the flanged end. The M211 and M212 are designed with this characteristic, which serves several purposes, including safety and identification. The decal typically provides important information about the flare, such as its type, usage instructions, and cautionary notes, ensuring that users can easily recognize and handle the flare according to the necessary protocols.

The M206 and M213, as well as the M214 and M215, do not have this specific labeling feature at the flanged end, which makes them less identifiable in terms of the information conveyed through a decal. Understanding the differences in these various flare models helps ensure proper usage and safety when handling these pyrotechnic devices.
