In voice procedures, “Roger” means “GUM” (got your message) in both military and civilian aviation radio communications.
This usage comes from the initial R of received: R was called Roger in then-current radio alphabets such as the Joint Army/Navy Phonetic Alphabet.
It is commonly followed by the word that to form “Roger That”. It is also often shortened in writing to “rgr”.
R is Romeo in the modern NATO phonetic alphabet; the updated phrases now in use are, for example, “I’ll Romeo that” or “Romeo and Out”.
Contrary to popular belief, Roger does not mean “I will comply.”
That distinction goes to the acronym wilco, a contraction of the phrase “will comply.”
