My Flashcards

Definition

Meaning

Weapons fire (such as bullets, missiles, bombs) from one's own side or allies that causes accidental injury or death to one's own personnel.

Any unintentionally harmful action or criticism coming from within one's own group, team, organization, or social circle.

Linguistics

Semantic Notes

The term is an oxymoron, combining the positive 'friendly' with the destructive 'fire'. It inherently describes an accident or tragic mistake, not intentional harm.

Dialectal Variation

Differences

Connotations

Strongly negative, implying tragic error, systemic failure, or breakdown in communication/identification.

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate literally as 'дружественный огонь' – it is not idiomatic. The correct Russian military/journalistic term is 'огонь по своим' (fire on one's own). Figuratively, use 'удар в спину от своих' (a stab in the back from one's own).

Common Mistakes

  • Using it to describe intentional betrayal (it must be accidental).
  • Using it for verbal criticism only (the core meaning involves physical harm, though figurative use is accepted).
  • Confusing it with 'crossfire' (which is fire from multiple directions, not necessarily from one's own side).

FAQ

Frequently Asked Questions

Yes, by definition. It refers to inadvertent firing upon one's own forces. Intentional attacks on one's own side are termed 'fragging' or mutiny, not friendly fire.

Yes, figuratively. It is commonly used in politics, business, and sports to describe damaging criticism or actions that come from within one's own group, harming its interests unintentionally.

'Friendly fire' originates from your own side. 'Crossfire' is firing from two or more directions which may involve both enemy and friendly forces; being caught in crossfire doesn't specify the source of the harmful fire.

In military jargon, yes, but 'fratricide' is more formal and clinical. 'Friendly fire' is the standard term in journalism and common parlance. Figuratively, 'friendly fire' is preferred.
