What are the three safeties for US Army hand grenades?

The correct response identifies the critical safety components associated with US Army hand grenades. Understanding these components is crucial for ensuring safe handling and operation of the grenades.

The pin, spoon, and clip are the three main safety mechanisms. The pin is a critical safety feature that prevents the spoon from being released; it must be pulled to allow the spoon to function properly. The spoon, also known as the lever, is attached to the grenade, and when the pin is removed, it allows the spoon to be released, initiating the detonation sequence after a brief delay. The clip, often used to secure the spoon or keep it in place, plays a supportive role in preventing accidental release of the lever.

Each of these elements works in concert to ensure that the grenade does not unintentionally detonate. Understanding their role is vital for both safety and effectiveness in using hand grenades. Other options present different combinations of terms, but they do not accurately capture the standard terminology related to grenade safety, thus reinforcing the validity of the selected answer.
