About cadre

A cadre is the complement of commissioned officers and non-commissioned officers of a military unit responsible for training the rest of the unit. The cadre may be the permanent skeleton establishment of a unit, around which the full unit can be built if needed. In countries which have conscription, a cadre may comprise the permanent staff of a regiment who train the conscripts assigned to it. The term comes from the French expression en cadre, with the same meaning.
