Defilade Meaning Dictionary Explained Beyond Simple Terms
The word defilade in a dictionary usually means protection gained by placing troops, vehicles, or fortifications behind terrain or another obstacle so they are hidden from enemy observation or fire; as a verb, it can also mean to arrange something for that protection.
Plain meaning
In everyday dictionary language, defilade is a military term tied to cover, concealment, and protection. A position in defilade is often behind a hill, ridge, bank, wall, or similar obstacle that blocks direct line of sight or fire.
What dictionaries miss
Most short definitions stop at "protected from fire," but the term is more precise than that: it describes both a position and a tactical arrangement, and it can refer to protection from observation as well as from fire. That is why military references often distinguish between the noun sense, the verb sense, and the related idea of a vertical distance by which something is concealed.
In practical terms, defilade is not just "hiding"; it is using terrain intelligently so a force can reduce exposure while preserving the ability to operate. That distinction matters in doctrine, where cover, concealment, and geometry all affect survivability.
Dictionary senses
| Sense | Definition | Plain example |
|---|---|---|
| Noun | Protection or shielding from enemy observation and fire provided by an obstacle. | A vehicle parked behind a ridge is in defilade. |
| Verb | To arrange fortifications or forces so terrain protects them from enemy fire or observation. | The trench line was defiladed behind the slope. |
| Tactical concept | A defensive posture that reduces exposure to hostile fire while using the ground for protection. | A unit moves to the reverse slope to gain defilade. |
How to use it
- Use defilade when discussing military terrain, fortifications, or protected firing positions.
- Use it to describe both concealment and protection, not concealment alone.
- Use the verb form when something is deliberately arranged for that protection.
Related terms
Enfilade is the closest opposite: it describes fire directed along the long axis of a formation, increasing exposure. Defilade is the corrective idea, where terrain or barriers break that line of fire and reduce vulnerability.
Quick history
The term appears in older military writing on fortification and remains active in modern doctrine. Contemporary reference sources still define it in terms of shielding from hostile fire, which shows that the word has retained its tactical meaning rather than becoming obsolete jargon.
Bottom line
If you are looking for the dictionary meaning of defilade, the safest plain-English definition is "a protected position or arrangement behind terrain or an obstacle that shields against enemy observation or fire." That is the core meaning dictionaries give, and the part most readers miss is that it describes both the position and the act of creating it.
