Select all items that are considered military munitions (MM).

The choice that identifies military munitions effectively encompasses a wide range of items that are categorized as munitions used by the military. Military munitions include any items or substances used for armed conflict, which are designed for the purpose of explosive or incendiary effects.

The inclusion of explosives and pyrotechnics is essential because these materials are explicitly designed for military use, providing destructive capabilities or serving utility functions, such as signaling or illumination. Chemical munitions and agents are also categorized under military munitions due to their use in warfare and their potential to cause harm through chemical reactions.

Riot control agents, while often considered non-lethal, are also included in this category because they are utilized by military and law enforcement for crowd control purposes. Thus, the correct response accurately captures the comprehensive scope of military munitions, affirming that military munitions encompass various types, including explosives, pyrotechnics, chemical agents, and riot control substances.
