Learning

Memory Aids

Mnemonic

Think of a soldier filing behind a hill to be safe: DE-FILE-ADE. 'De' (down/behind) + 'file' (as in a line of soldiers) + 'ade' (action) = the action of getting soldiers behind cover.

Conceptual Metaphor

PROTECTION IS BEHIND A BARRIER; TERRAIN IS A SHIELD.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'дефиле' (a fashion show catwalk). The Russian military term is 'дефилирование' or more commonly 'укрытие от наблюдения и прямого огня'. The English word is a false friend.

Common Mistakes

  • Using it as a general synonym for 'hide'.
  • Confusing it with 'defile' (to make dirty or march in a line).
  • Pronouncing it as /ˈdiːfaɪleɪd/.

FAQ

Frequently Asked Questions

No, it is a very low-frequency, specialised term used almost exclusively in military contexts.

'Cover' is a broader term for protection from fire. 'Defilade' is a specific tactical subset of cover, referring to protection achieved by positioning behind a terrain feature so that you cannot be seen or hit by direct fire from a particular direction.

Yes. As a verb: 'to defilade the troops'. As a noun: 'the troops were in defilade'.

The tactical opposite is 'enfilade', which means to be exposed to fire along the longest axis of a formation or position. In general terms, 'exposed' is an antonym.
