What describes ammunition where the case is physically attached to the projectile, typically by crimping?

Fixed artillery ammunition is characterized by the physical attachment of the cartridge case directly to the projectile, commonly achieved through a process known as crimping. This design ensures the projectile and the propellant remain securely together, allowing for reliable loading and firing in artillery systems.

In fixed ammunition, the entire assembly is loaded into the firing chamber as one unit, minimizing the potential for misalignment or issues during the firing process. This method enhances the structural integrity of the ammunition, ensuring that the pressures generated upon ignition are effectively contained and directed, promoting consistent operation and accuracy.

Understanding the definition and use of fixed ammunition is vital for anyone in the field of explosive ordnance disposal as it informs procedures relating to safety, handling, and operational tactics. Other types of ammunition, such as semi-fixed or loose ammunition, do not feature this integral crimped connection, which affects their loading processes and handling precautions.
