“Alfa, Bravo, Charlie …” is an alphabet you may already know and understand.

These words represent the letters A, B, and C in the International Radiotelephony Spelling Alphabet, more commonly known as the NATO phonetic alphabet. It was standardized in 1956 with sounds that are similar in English, French, and Spanish, and the military still uses it today to omit misunderstandings over the radio.

If you aren’t using it already, this would be a good one to adopt for those customer service calls where you need to read your 17-digit confirmation code that somehow is made up of letters that all sound the same.

Or how about when someone says, “Meet me here at 1400?” The military time system, which uses the 24-hour clock, is another method used to prevent mistakes or confusion between a.m. and p.m. times, as critical missions leave no room for miscommunications. This is another one that may come in handy to civilians with a propensity for setting their alarm at the wrong time or showing up to appointments at 7 p.m. instead of 7 a.m.

The centuries-long history of the U.S. military has allowed those who serve to essentially develop their own language. There is plenty more to unpack regarding that language.

You can listen to every episode of Florida’s Fourth Estate in the media player below:

Stacker consulted members of various military branches as well as existing military dictionaries to find 40 terms, phrases, acronyms, and nicknames that you may want to add to your repertoire. Some are used in official military procedures, while others are slang terms and acronyms that only members of one branch or another might know. Other terms have crept into the everyday vernacular of civilians, shedding their recognizable military origins while contributing to what some call the “militarization of society.”

Read on to learn more about these military terms, their histories, and their sometimes surprising meanings.

An expression you may already be using, legend has it that this saying was derived from having service members bite a bullet during battlefield surgery to distract them from pain. The aphorism means to accept the inevitable or impending suffering and move past it quickly and with fortitude.

BOG, or boots on the ground, refers to combat troops who are deployed in another country. Though the phrase has been criticized for obscuring the humanity of deployed soldiers by referring to them as "boots," it is still commonly used.

Chow down

Another one on the list you may already be using, this phrase is understood to have military origins. The literal meaning is to sit down and eat. "Chow" is a popular word for food for members of the armed forces and is used interchangeably with "mess." Both words lend themselves to dining places: "chow hall" or "mess hall."

Dear John

"Dear John" is when one's significant other breaks up with them through a letter, often when the person is deployed or training away from home. The term (often used as a verb; to "Dear John someone") was popularized by the 2010 film starring Amanda Seyfried and Channing Tatum.

Dud

"Dud" has been adopted to mean something that does not work. The technical origin is from the Middle English word "dudde," which refers to worn-out clothing and was later expanded to include weapons that were worn out or dysfunctional. Now dud is synonymous with junk and can be applied to anything (or anyone) that does not work as it was supposed to.

Some say the term was applied to weapons from the sound a bomb makes when it does not go off (a "thud" or a "dud").
