Is "roger" equivalent to "Ok"? I hear it in war movies, movies like Star Wars Clone Wars, and in war games.

It's not necessarily military, it's more radio slang.

In certain radio alphabets Roger stands for the letter R, which in radio communications stands for received.

    I didn't know this - I actually thought it meant "Ok" (and I am a native english speaker). Thanks! Jun 28, 2011 at 21:09

    @BlueRaja: The meaning is similar, and because of the common use of this in war movies etc. it has also been quite popular to use it in daily speach as a synonym to "OK".

    @nico: Certainly 'slang' is slang for 'jargon', but I don't think 'slang' is jargon for 'jargon'. Oct 5, 2011 at 12:52

"Roger" is from WWII-era radio code for the letter "R", and was used as a more-understandable shorthand for "Received", an acknowledgement of the message. More recently, radio shorthand has moved to "copy" (an exact synonym) or "wilco" (short for "will comply" and appropriate for commands).

    Also: "roger wilco" for "understood and will comply."

    Also "roger roger" if you're a cool Star Wars patois-speaking robot.

    @The Raven 'Note that "ROGER" and "WILCO" are mutually exclusive, since WILCO includes the acknowledgement of ROGER.' from: en.wikipedia.org/wiki/Procedure_word#WILCO

From Wikipedia

"Roger" means "I have received all of the last transmission" in both military and civilian aviation radio communications. This usage comes from the initial R of received: R was called Roger in the radio alphabets current at the time, such as the Joint Army/Navy Phonetic Alphabet. It is also often shortened in writing to "rgr". R is Romeo in the modern NATO phonetic alphabet.

Yes, roger or roger that means message received. From Merriam-Webster:

used especially in radio and signaling to indicate that a message has been received and understood
