In addition to explosive cartridges used in small arms, exploding ammunition can include rocket-propelled grenades or mortar shells.
[1] Exploding ammunition was used by both Allied and German forces during World War II, by Iraq, and Afghanistan; possibly by the Soviet Union in Afghanistan as well.
Exploding ammunitions were used by the United States in Vietnam (Project Eldest Son).
[4] In addition to sale through black market channels, exploding ammunition may be distributed to enemy forces by being "lost" during transport, or on the battlefield where it may be left behind after a retreat.
Using a small charge which only jams the weapon is sometimes done when the chance that the spiked ammunition may fall into friendly hands is high, for example, when a case of ammunition is "lost" by appearing to have fallen from the back of a truck.
