In this chapter, we are implementing a weapon system with attachments. We have a couple of specifications to consider, such as the following:

• We need to be able to attach multiple attachments to a weapon.
• We need to be able to add and remove them at runtime.

The Decorator pattern offers us a way to fulfill these two core requirements. Therefore, it's a pattern to consider when implementing a system in which we need to support the ability to add and remove behaviors to an individual object in a dynamic manner.
