Which proword indicates that the message was successfully received?

The proword that indicates the message was successfully received is "Acknowledge." This term is used in communications to explicitly confirm that the receiver has understood and received the transmitted message without requiring any repetition or clarification. When "Acknowledge" is used, it reassures the sender that their communication has been effectively received and comprehended.

In tactical communications, clear confirmation of receipt is crucial for operational effectiveness, ensuring that all parties are on the same page and can proceed accordingly. "Acknowledge" serves as a clear and direct way to convey this understanding.

Other terms mentioned could imply receipt but do not carry the same unequivocal confirmation as "Acknowledge." For instance, "Copy" might suggest that the message was received but does not explicitly state comprehension, while "Affirmative" is typically more associated with agreeing to a command or statement rather than confirming receipt of a message. "Repeat" indicates that the sender is requesting the message to be sent again, highlighting a lack of confirmation rather than success in receipt.
