Final answer:
The M67 is a hand grenade used by the United States Armed Forces. It is known for producing deadly shrapnel upon explosion and is used for offensive and defensive purposes in military operations.
Step-by-step explanation:
The M67 is a type of hand grenade used by the United States Armed Forces. It is commonly referred to as the "frag grenade" due to its ability to produce fragmented deadly shrapnel upon explosion. The M67 is made of a thin outer casing filled with explosives and a fuse mechanism for ignition.
When thrown, the M67 grenade has a detonation time of about 4 to 5 seconds, allowing the thrower to get to a safe distance. Upon detonation, the explosive filling transforms into high-velocity metal fragments that can cause significant damage to personnel and structures within its blast radius.
The M67 grenade is widely used for both offensive and defensive purposes in military operations. It is designed to incapacitate or eliminate enemy combatants and can be particularly effective in close-quarters combat situations.
