The phrase "Roger that" is widely used for confirmation during radio negotiations. But where did it come from and where does a certain Roger come from?
The word "Roger" comes from the phonetic alphabet that was used by ground and ground personnel of the US Army during World War II to organize two-way communications. The fact is that radio operators needed extremely clear ways of presenting information without the possibility of misinterpretation.
For example, since 1957 NATO has used the phonetic designations of the letters of the alphabet - Alpha, Bravo, Charlie, etc. where "R" corresponds to the word "Romeo", but before that, "Roger" was used instead.
The use of "R" as confirmation of receipt of information appeared even earlier in the era of Morse code, when it was decided to confirm the receipt of long and complex messages with several memorable letters.
By replying to a message with the letter "R", for example, one could simply let the sender know that his message was received. With the advent of two-way voice radio communication, the concept has been preserved, but with the word "Roger" instead of just one letter "R".
Although Roger was later replaced by Romeo, the widespread use of two-way radio communications during World War II made the phrase super popular. Today it sounds a little differently - "Roger that", but translated into Russian it still means "I understand you."
