What type of grenades does the M-67 refer to?

The M-67 is specifically known as a fragmentation grenade. It is designed to disperse shrapnel upon detonation, making it effective for anti-personnel purposes. When the grenade explodes, the steel casing breaks apart, creating high-speed fragments that can injure or kill nearby individuals. This characteristic distinguishes it from smoke, flashbang, and incendiary grenades, which serve different tactical functions. Smoke grenades are meant for obscuring vision, flashbangs are designed to disorient individuals with a loud bang and bright flash, and incendiary grenades create fires or heat rather than fragments. The design and intended use of the M-67 clearly align it with fragmentation capabilities, confirming the choice of this option as the correct answer.
