Jankers

In the British Armed Services, "Jankers" or "Restrictions of Privileges" refers to an official disciplinary measure employed for minor breaches of military discipline. This contrasts with more severe punitive actions like "detention," which is reserved for more serious or criminal offenses. When a service member is "on jankers," it indicates that they have been subjected to disciplinary action initiated by a non-commissioned officer (NCO) or occasionally a commissioned officer (referred to in service slang as "being put on a fizzer"). The alleged offence is documented on a Charge Report (Army or RAF Form No. 252).

Following a hearing before an officer, the decision to impose the punishment is made based on the evidence presented and any mitigating circumstances. The use of acronyms is common in the British military, as in many organizations, and such abbreviations often become part of the standard jargon. The term "Jankers" may have originated as a shorthand for "Justice Administered by NCO" and subsequently evolved into its colloquial form.
