Brigadier ( /brɪɡəˈdɪər/) is a senior military rank, the meaning of which is somewhat different in different military services. The brigadier rank is generally superior to the rank of colonel, and subordinate to major general.
A brigadier typically commands a brigade consisting of three battalions (approximately 3,000 troops). Many countries use the rank brigadier general rather than brigadier, and prior to the 1920s, so did members of the Commonwealth.
