sirpaleet

Sirpaleet, known in English as shrapnel, are fragments produced when an explosive device detonates. They are typically metal pieces that are propelled at high velocity and can cause penetrating injuries over a wide radius. The concept encompasses both pre-formed fragments from a bursting shell and the debris created by the explosion of various ordnance.

Origin of the term lies in the name of Henry Shrapnel, a British artillery officer who, in 1784, developed a hollow exploding shell that released miniature projectiles in flight. The word later came to describe fragmenting munitions in general, and was adopted into Finnish as sirpaleet.

Mechanism: Early shrapnel shells carried a cargo of lead balls and a timed fuse; upon bursting, the pellets were hurled forward in a cone. Modern fragmentation weapons rely on casing fragmentation and the detonation of the warhead to generate a large number of high-velocity fragments, rather than a pre-set payload.

Contexts and types: Shrapnel is produced by artillery shells and aerial bombs, as well as certain guided missiles and cluster munitions that fragment upon detonation. IEDs and improvised devices can also create shrapnel-like hazards through the dissemination of metal fragments.

Effects and protection: Shrapnel injuries range from minor lacerations to life-threatening trauma, especially to exposed areas such as the head, neck, and limbs. Protective measures include armor, helmets, reinforced structures, and safe standoff distances, along with medical care to manage bleeding and infection.
