Spain uses brigada among its NCO grades, although the related title brigadier can denote a general officer in other armed forces. In this reading, the title denotes a brigade's senior NCO, below the higher Spanish enlisted titles. First-sergeant, sergeant, several corporal grades and two sailor grades extend the hierarchy below it. Clusters of intermediate officer or NCO grades may reflect conscription, national service or the importance once attached to prestigious titles. A rank table needs the navy's historical setting to explain why distinctions accumulated where they did.
