Define primary fragmentation.

Define primary fragmentation.

• A. Fragmentation produced by fragments of IED/explosive container
• B. Objects propelled from around detonation point, as well as fractured pieces from target material
• C. Device fabricated in manner incorporating destructive/lethal/incendiary chemicals designed to kill/destroy/distract
• D. Power source gives power to initiator

Answer: (A)

Primary fragmentation is the debris that comes directly from the explosive device itself—specifically the fragments from the IED’s own casing or container when it detonates. This is the material ejected because the device’s body breaks apart under the blast, independent of anything nearby. That’s why the best choice describes fragmentation produced by fragments of the IED/explosive container. The other options describe related ideas that aren’t about the device’s own debris: one points to debris from surrounding objects and target material (secondary fragmentation), another refers to the device’s destructive purpose, and the last mentions the power source for initiation rather than the fragmentation produced.
