Achief of defence (orhead of defence) is the highest rankedcommissioned officer of a nation's armed forces. The acronym CHOD is in common use withinNATO and theEuropean Union as a generic term for the highest national military position within the NATO and EU member states, rather than the actual term used for individual positions. Thus, irrespective of the formal national designation of that position is some variation onCommander-in-Chief,Chief of Staff,Supreme Commander, or something else, they can all be referred to unambiguously as CHODs in NATO and EU terminology, although other terms are sometimes also seen within NATO. Thus, theChairman of the Joint Chiefs of Staff is the CHOD of theUnited States, theChief of the Defence Staff is the CHOD of theUnited Kingdom, theInspector General of theBundeswehr is the CHOD ofGermany, and theChief of Defence (Forsvarssjefen) is the CHOD ofNorway.
Both NATO and the EU occasionally hold CHODs meetings of theNATO Military Committee and theEuropean Union Military Committee respectively.

Withinmember states of NATO, the following national positions are the CHOD positions. Sometimes more than one form of translation into English is encountered.
