Explosive train primers are classified based on:

The classification of explosive train primers based on the way they are initiated is fundamental to understanding their operation in munitions systems. This classification focuses on how primers react to initiate an explosive chain reaction. Different initiating methods include electric, non-electric, and shock initiation, each playing a crucial role in the overall function and safety of explosive systems.

For instance, electric primers use electrical energy to initiate detonation, while non-electric primers rely on physical means, such as a shock wave or friction, to achieve the same effect. Understanding these initiation methods is essential for safety protocols, operational effectiveness, and logistics management in munitions handling and deployment. Therefore, this classification directly impacts the design and application of explosive devices, making it a critical aspect of munitions systems training.
