The 14 Marine Corps Leadership Traits, Applied at Work
The 14 traits are justice, judgment, dependability, initiative, decisiveness, tact, integrity, enthusiasm, bearing, unselfishness, courage, knowledge, loyalty and endurance. Every one of them is a behavior somebody else can observe in you, which is exactly why the Marine Corps chose them and why they survive the trip into an office.
What are the 14 Marine Corps leadership traits?
The 14 Marine Corps leadership traits are justice, judgment, dependability, initiative, decisiveness, tact, integrity, enthusiasm, bearing, unselfishness, courage, knowledge, loyalty and endurance. Marines learn them in that order through the mnemonic JJ DID TIE BUCKLE, one letter per trait, because a list you cannot recall under pressure has stopped being a standard. Every one of the fourteen is something another person can watch you do or fail to do, which is the reason the United States Marine Corps chose these rather than a set of values.
The pages that rank for this term give you the list and the definitions. This post does the other half. I enlisted in 1988 and trained as a Marine sniper, and the useful thing I can add is what each trait looks like when it is missing, because that is the version you will recognize in a product review when a launch date slips. The 11 leadership principles are a separate list, covered in Marine Corps Leadership Principles.
Why the Corps chose traits you can watch
A value is a claim. A trait, the way the Corps uses it, is an observation. Nobody gets graded on believing in dependability. They get graded on whether the thing arrived. That distinction is why the list can be taught to a nineteen-year-old and used by a sergeant in the same afternoon.
It is also why correction stays survivable. Saying a Marine has a dependability problem points at a behavior with a fix. Saying he let the unit down points at a person and starts an argument. Amy Edmondson's 1999 paper in Administrative Science Quarterly defined psychological safety as a shared belief that the team is safe for interpersonal risk-taking, and a vocabulary that separates the error from the person is one of the cheaper ways to protect that belief while still holding a standard.
The 12 Cs of Trust make the same bet for civilian teams. Each of the twelve is a behavior somebody else can watch: whether the promise was kept, whether the hard thing was said early, whether the loop was closed.
The 14 traits at work, trait by trait
Fourteen traits, with what each one looks like present and absent. Keep this beside you in your next status meeting and you will spot at least four of them in the first ten minutes.
- Justice. Present: the same standard held for your strongest performer and your weakest. Absent: quiet exceptions for whoever is hardest to replace.
- Judgment. Present: decisions that still hold up when the context shifts. Absent: a defensible answer that everyone could see was wrong by Thursday.
- Dependability. Present: the thing arrives when it was promised, including the week it is inconvenient. Absent: the team builds a private buffer around your dates.
- Initiative. Present: somebody fixes the broken handoff without waiting for a mandate. Absent: everyone can name the problem and nobody owns it.
- Decisiveness. Present: a decision announced clearly enough that people can act on Monday. Absent: a meeting that ends in let us circle back, for the third time.
- Tact. Present: a hard message delivered so it can be heard and acted on. Absent: either a softened version nobody decodes, or a blunt one that starts a defense.
- Integrity. Present: the same account of the project given to the board and to the team. Absent: two versions, and everyone knows which room they are sitting in.
- Enthusiasm. Present: visible interest in work you did not choose. Absent: a leader who signals in advance which projects are beneath them.
- Bearing. Present: the same person at 0300 when the plan collapses as at 0900 when it is fine. Absent: a room that reads your face before it reads the data.
- Unselfishness. Present: credit routed to the person who did the work, in front of the people whose opinion they care about. Absent: we becomes I somewhere between the team and the executive summary.
- Courage. Present: naming the slipped date first, before anyone has to drag it out of you. Absent: a status marked green that everyone privately scores amber.
- Knowledge. Present: enough command of the work to be useful inside the argument. Absent: a leader who can only discuss the summary slide.
- Loyalty. Present: defending your team's decision in the room where they are not. Absent: agreeing upward, then delivering the news downward as though you had been a bystander.
- Endurance. Present: the standard still holds in month nine of a hard project. Absent: the standard turns out to have been a launch-week performance.
The four that civilian leaders get wrong most often
Tact. The common failure is treating tact as softening. In a quarterly review I sat in on, a senior leader delivered a performance concern so gently that the person walked out believing they had been complimented on their resilience. Tact is the selection of wording that lets a hard message land and get acted on, which usually means being more specific rather than gentler.
Bearing. Civilian leaders hear bearing as posture and dress, which is the least interesting part of it. The Corps means the impression you make through conduct, continuously, and the version that matters at work is what your face does when the number is bad. A team reads the leader before it reads the dashboard. If your reaction is the first data point they get, they will start managing your reaction instead of the problem.
Unselfishness. This one fails in the executive summary. Four people do the work, the summary goes up with one name on it, and the four find out from a forwarded email. I have watched a single instance of that burn two years of accumulated goodwill in a week. The fix is unglamorous: name the people in the room where naming them costs you a little attention.
Endurance. The trait is stamina against fatigue and stress, and at work it shows up as whether your standard survives month nine. Almost anyone can hold a standard during launch week. The question is whether the Friday summary still goes out in the middle of a bad quarter, when nobody would blame you for dropping it. That is the week it is actually being measured.
How to run a self-check against the traits this week
The five-minute version. Read the fourteen and, for each, write down the last specific instance where somebody could have observed it in you. Not where you believe you hold it. Where it was visible. Any trait for which you cannot produce an instance from the past month is the one to work first, and it is usually tact or endurance.
The fuller version brings other people in, which is the only version that means much. Pick three people who see you work: one senior, one peer, one who reports to you. Ask each for the two traits they would name as your strongest and the one they would name as your weakest, and ask for an instance with every answer. If the same trait comes back twice from different directions, you have your next eight weeks.
One caution, because people ask. The 14 traits are not a scoring scale and the Marine Corps has never offered them as one. They are a vocabulary. The scoring instrument here is a separate thing: the 12 Cs of Trust, the behavioral frame inside the TrustFlow™ methodology, rolled up into the Team TrustFlow Index on a 1.00-5.00 scale with bands for Constrained Trust, Developing Trust and Sustained TrustFlow. Use the traits to see yourself and the trust scorecard to see the team. Confusing the two gives you a number with nothing underneath it.
FAQ
What are the 14 leadership traits of the Marine Corps?
Justice, judgment, dependability, initiative, decisiveness, tact, integrity, enthusiasm, bearing, unselfishness, courage, knowledge, loyalty and endurance. The United States Marine Corps teaches them in that order, and every Marine learns them as formal doctrine rather than picking them up by exposure. They sit alongside a separate list of 11 leadership principles, which describe what a leader does rather than the qualities a leader is expected to build.
What does JJDIDTIEBUCKLE mean?
It is the mnemonic Marines use to recall all 14 leadership traits in order, one letter each: Justice, Judgment, Dependability, Initiative, Decisiveness, Tact, Integrity, Enthusiasm, Bearing, Unselfishness, Courage, Knowledge, Loyalty, Endurance. The device exists for a practical reason. An exhausted nineteen-year-old cannot retrieve a paragraph of values language under pressure, but can retrieve fourteen words through a phrase.
What is the difference between the 14 traits and the 11 principles?
The 11 principles are instructions. They are verb phrases telling a leader what to do, like keep your Marines informed or ensure the task is understood, supervised, and accomplished. The 14 traits are nouns describing qualities a leader is expected to build, like dependability and tact. The Corps teaches both because a leader with the instructions and none of the qualities runs a competent unit nobody follows any further than required.
Which leadership trait is hardest to develop?
Endurance, in my judgment, and I offer that as thirty years of observation rather than as data. Most leaders can hold a standard during launch week. Very few still send the Friday summary in month nine of a difficult project, when skipping it would cost them nothing socially. Tact runs a close second, because the common failure is mistaking it for softening a message rather than sharpening it.
Can you measure leadership traits?
Not with a scale from the Marine Corps, which has never published the traits as a scoring instrument. They are a vocabulary for observation and correction. Measurement on a team is a separate exercise with a separate instrument: the 12 Cs of Trust scored into the Team TrustFlow Index, on a 1.00 to 5.00 scale. Treating the traits as a score produces a number with nothing underneath it.
Do these traits apply outside the military?
Yes, because none of the fourteen depends on rank. Dependability, tact, unselfishness and the rest describe behavior anyone can observe in a colleague, and they hold in a product review as readily as in a squad bay. What does not carry over is the enforcement. A Marine cannot resign on a Thursday, and your team can, so a trait you fail to demonstrate has different consequences.
The value of the list is that it gives you words for something you were already noticing. You knew the status green was optimistic. You knew the summary had one name on it. Now you have a name for both, and a name is the start of a correction that does not turn into an argument.
