40 Military Terms and Their Meanings

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. 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.


One of the more familiar military terms is “AWOL,” an acronym for “absent without leave.” Someone who takes on this status is gone without permission, typically in the context of abandoning their post.

Azimuth check

An azimuth is an angular measurement in a spherical coordination system. While usually used as a technical term in land navigation, this phrase can generally refer to taking the time to stop and ensure the current task (whatever it may be) is being done right.

Beat feet

A fun-sounding rhyme, “beat feet” means to move from your current location quickly, as in to beat your feet on the pavement.

Bite the bullet

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.


Commonly used in the Marines, “boot” is a somewhat derogatory term for a novice service member, often one who is fresh out of boot camp. Depending on who you ask, it stands for “beginning of one’s tour” or “barely out of training.”

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.”


“Civvies” is a nickname for civilian (nonmilitary service members) outfits or clothing.

Coup de grace

“Coup de grace” translates in French to “stroke of grace” or “blow of mercy.” You may have heard this defined as a mercy kill, but the phrase is also applied to the final action necessary to finish a task.

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.


Short for dining facility, some military members use “DFAC” to refer to a “chow hall.”


“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”).


Exactly what it sounds like, “fangs” is a Marine Corps term for one’s teeth.

Fruit salad

Slang for the ribbons and medals on a Marine uniform due to the rich array of colors contrasting with the plain blue uniform.


“FTA” is an acronym for “failure to adapt.” Someone can be reprimanded or discharged for this lack of versatility, and some modern workplaces may use this terminology to evaluate employees.


While the origin of “FUBAR” is debated (one source said it was from the German word “furchtbar,” meaning frightful or terrible), it has now been popularized to stand for “f****d up beyond all repair/recognition.” This term can be heard used famously in movies like “Tango and Cash” and “Saving Private Ryan” and refers to a situation that has gone very wrong.

Full battle rattle

Another rhyme on the list, this one means to be wearing all of your battle gear.

Grab some real estate

A phrase often used to indicate that some sort of physically taxing punishment—often pushups—will ensue. The “real estate” is likely a patch of grass or an area of cement from which you will be expected to complete the punishment.

Groundhog Day

This term refers to repetitive, boring situations. The concept was popularized by a 1993 Bill Murray film of the same name.

Have someone’s 6

Meaning to have someone’s back, the phrase applies to physically watching the “6 o’clock” of someone on a mission or in battle. Using clock position, the 6 o’clock would indicate behind or below that person.


JAG stands for judge advocate general, or the military’s senior-most judicial officer. In the U.S., judge advocates are specially trained in military law and are usually appointed to a specific branch of the armed forces where they provide legal guidance and serve as lawyers in courts-martial. Judge advocates make up the JAG Corps.

KP duty

Kitchen Police duty, also known as Kitchen Patrol duty, is an often-dreaded task assigned to soldiers that involves preparing food to be cooked, serving meals, and cleaning up the kitchen and dining halls afterward. In the 1980s, some military branches began replacing military personnel on KP duty with civilian workers, ending the infamously hated job.


Short for Military Entrance Processing Stations, these centers are where those interested in enlisting in the military go to be evaluated. At MEPS, prospective enlistees take an exam called the Armed Services Vocational Aptitude Battery, which tests whether the military would be a good fit, and, if so, which branch is the best match.


“MREs” are packages of food for combat or other field positions, representing “meals ready to eat.”

Oxygen thief

An “oxygen thief” is witty, derogatory slang for someone who talks too much.


A permanent change of station, or PCS, is a normal part of being in the military and involves moving between one station and another or from a station to home. According to the Department of Defense, around a third of those in the military experience a PCS move each year. Most of the time, the cost of relocation is paid for by the government.


PT, also known as physical training, is not just tested during basic training. A Physical Fitness Test is administered several times a year for enlisted soldiers in several branches of the military. Each branch has different requirements for the test, but most involve different variations of running, push-ups, and sit-ups.


“Rack” is slang for bed. Beds in boot camp and on ships are notoriously uncomfortable, with the word rack summoning the vision of an uncomfortable piece of metal.


“Roger” or “Roger that” is used over the radio or phone to indicate that a message has been received and understood.


“Skate” or “skate by” means try not to do work. Some say it stands for “Seek cover, Keep quiet, Accept no responsibility, Take no action, Evade.”


“Skivvies” is a nickname for an undershirt or underwear that one wears under their uniform.


To “smoke” someone is to punish, particularly with physical exercise.


Similar to “FUBAR” the actual origin of “SNAFU” is debated, but it has come to mean “situation normal all f****d/fouled up.”

Soup sandwich

Another fun one to adopt, a “soup sandwich” is exactly what it sounds like—chaos or a mess. Just picture two pieces of bread holding soup in place.


Temporary Duty assignments are a type of military order that temporarily moves a servicemember away from their permanent duty station for a specific period of time. These can include instances of educational or training opportunities, as well as special missions.


“TS” stands for “top secret.” It is often applied to specific pieces of information but is also used in “TS/SCI-cleared,” which is a blanket top-secret security clearance.

Uncle Sam

“Uncle Sam” is a personification of the U.S. government and sometimes the U.S. military. Uncle and Sam begin with the country’s letters, and according to legend, it is actually meant to be Samuel Wilson, a meatpacker from New York who lived from 1766–1854.


“Voluntold” is exactly what it sounds like: an oxymoron combining the words volunteer and told. It is something one is asked to do voluntarily, but it has an unspoken understanding that it is not actually optional.


You may read this as hugs and kisses, but “XO” refers to an executive officer. In many militaries, the “XO” is the second in command and often in charge of day-to-day activities.


A “zoomie” is a fun way to say “pilot.” In the military, zoomie generally refers specifically to an Air Force member or an Air Force Academy graduate.
