Which type of grenade is shaped like an egg?

The type of grenade that is shaped like an egg is the illumination grenade. These grenades are specifically designed to produce a bright light to illuminate the battlefield during nighttime operations or in low-light conditions. The egg-shaped design allows for a more efficient dispersion of the chemical compounds that create the light when the grenade is deployed.

In contrast, fragmentation grenades are typically spherical or cylindrical and are designed to produce shrapnel upon detonation; cylindrical grenades maintain a uniform shape to facilitate a specific burst pattern. Smoke grenades are often cylindrical as well and are designed for creating smoke screens, differing significantly in form and function from the illumination grenade.

The illumination grenade's unique shape is not only for aesthetic purposes but also serves a functional role in ensuring the effective engagement of its intended use, which is critical during tactical operations where visibility is compromised.
