Which of the following is a type of grenade used in military operations?

The correct answer is that all of the listed types of grenades—incendiary, explosive, and smoke—are indeed used in military operations. Each type serves a distinct purpose on the battlefield.

Incendiary grenades are designed to create fire and are often used to disrupt enemy formations or destroy equipment. Their effectiveness lies in their ability to ignite flammable materials, making them a powerful tool in certain combat scenarios.

Explosive grenades are primarily intended to cause damage through blast and fragmentation. They are the most commonly recognized type of grenade and are used for direct assaults against personnel and vehicles. The explosive charge inside these grenades detonates on impact or after a designated time, maximizing the blast radius for maximum effect.

Smoke grenades are utilized for creating visual obscuration on the battlefield. They can provide cover for troop movements, signal positions, or mark targets without causing direct physical harm. The smoke can thwart the adversary's line of sight and communication.

Each of these types plays a critical role in military tactics, highlighting the versatility of grenades in various operational contexts. This comprehensive utility justifies that all mentioned options are valid types of grenades used in military operations.
