What does a complete cluster bomb unit (CBU) consist of?

A complete cluster bomb unit (CBU) consists of a quantity of small submunitions and a dispenser. The purpose of the dispenser is to release the submunitions effectively over a designated area, allowing them to spread out and engage multiple targets. This configuration is designed for both effectiveness and efficiency in delivering munitions across a wide area, maximizing the impact on the battlefield.

The design of a CBU integrates the capabilities of submunitions to function both autonomously and as a collective unit, enabling the delivery system to engage various targets with lower collateral damage. In contrast, the other options do not meet the definition of a complete CBU due to either lacking the necessary components (like a dispenser) or involving a different weapon system entirely. Thus, understanding that a CBU must include both submunitions and a dispenser is crucial for grasping its operational use and effectiveness in military operations.
