Which type of grenade is commonly used by infantry units?

The M67 Fragmentation Grenade is the standard grenade used by infantry units primarily due to its effectiveness in combat situations. This type of grenade is designed to produce a lethal blast radius and scatter shrapnel, making it highly effective against enemy personnel in open areas or cover. The design features a spherical body that allows for an even distribution of fragments upon detonation, maximizing its impact in a combat scenario.

Infantry units utilize the M67 for its versatility in various operational environments, and its reliability has been proven through extensive use across multiple conflicts. While other grenades, such as the M84, serve specific purposes like stunning or disorienting the enemy, and the M18 provides cover with smoke, the M67 remains the primary choice because it directly addresses threats through lethal force. This makes it essential for infantry combat effectiveness, especially when engaging dispersed enemy forces or in close-quarter battles. The AN-M14 TH3 incendiary grenade, while useful in certain situations such as starting fires or destroying equipment, does not have the broad applicability or effectiveness of the M67 for general combat scenarios faced by infantry units.
