UA, AWOL, and desertion all involve unauthorized absence from military duty, but they are not interchangeable. Under the Uniform Code of Military Justice (UCMJ), each term reflects different elements, intent, and potential consequences. The distinction matters because how an absence is classified can affect the charges filed and the severity of punishment.

Understanding the differences can help service members and families evaluate what an allegation may involve and what comes next.

What Is UA (Unauthorized Absence)?

Unauthorized Absence (UA) is the term most commonly used in the Navy and Marine Corps. It refers to a service member who is absent from their assigned duty station without proper authority.

Key Elements

  • Absence from a required place of duty
  • Lack of permission or authorization
  • Knowledge of the duty requirement

Typical Fact Patterns

  • Missing a scheduled watch or duty shift
  • Failing to return from authorized leave on time
  • Leaving a duty station without approval

UA is often charged under Article 86 of the UCMJ, which governs unauthorized absence across all branches, even if different terminology is used.

What Is AWOL (Absent Without Leave)?

AWOL (Absent Without Leave) is the term more commonly used in the Army and Air Force. Functionally, it is the same offense as UA under Article 86.

Key Elements

  • Failure to be at the required place at the prescribed time
  • Absence without proper authority
  • Awareness of the duty obligation

Typical Fact Patterns

  • Not reporting for duty at the start of a shift
  • Remaining absent after leave expires\
  • Leaving a unit without authorization

While “UA” and “AWOL” are often used differently across branches, both describe an unauthorized absence without the additional intent required for more serious charges.

What Is Desertion?

Desertion is a more serious offense under Article 85 of the UCMJ. It involves an unauthorized absence accompanied by specific intent that goes beyond mere absence.

Key Elements

  • Unauthorized absence
  • Intent to remain away permanently
  • Intent to avoid hazardous duty or important service

Typical Fact Patterns

  • Leaving a unit with no intention of returning
  • Avoiding deployment or combat assignment
  • Remaining absent for an extended period with evidence of permanent separation

Intent is the critical distinction. A prolonged absence alone does not automatically equal desertion, but it may be used as evidence of intent.

Why the Label Matters

The classification of an absence affects both how the case is charged and the potential exposure to punishment.

  • UA/AWOL (Article 86) generally involves administrative or non-judicial handling in less severe cases, though court-martial is possible
  • Desertion (Article 85) is treated as a serious criminal offense and is more likely to be prosecuted at a court-martial

Potential consequences may include:

  • Confinement
  • Reduction in rank
  • Forfeiture of pay
  • Punitive discharge

The difference between a short-term unauthorized absence and a charge involving intent to desert can significantly change the stakes.
