Which type of artillery ammunition has a case that is not permanently attached to the projectile?

The type of artillery ammunition where the case is not permanently attached to the projectile is categorized as semi-fixed artillery ammunition. This type of ammunition consists of a projectile, which is separate from the propellant charge contained within a cartridge case. The main advantage of this design is that it allows for flexibility in terms of loading different projectiles with the same case, thereby enabling adjustments in terms of range and type of firepower based on the tactical requirements.

In contrast, fixed artillery ammunition has the projectile and cartridge case permanently joined together, which simplifies the loading process but offers less versatility. Separate-loading ammunition emphasizes that the projectile and propellant are separate, similar to semi-fixed but with even more flexibility in terms of customizing firepower. Loose loading refers to a practice whereby components are carried freely and assembled only for firing, but typically not categorized specifically as a type of ammunition.

Understanding the distinctions between these types enhances the ability to select the appropriate ammunition for varying situations in the field effectively.
