What is indicated by the expression "roger, wilco"?

The expression "roger, wilco" combines two key elements of communication in a clear and concise manner. "Roger" indicates that the message has been received and understood, while "wilco," short for "will comply," confirms the intention to follow the instructions provided. Together, they communicate not only acknowledgment of the message but also a commitment to act on it.

In the context of effective communication, especially in fields such as aviation and military operations, clarity and brevity are paramount. Thus, using the phrase "roger, wilco" effectively conveys to the sender that the recipient not only understands the instructions but is also prepared to execute them. This is why the answer is correct, as it encapsulates both the acknowledgment and the affirmation of compliance in a single expression.
