Brigadier (abbreviated Brig) is a senior rank in the British Army and the Royal Marines. Brigadier is the superior rank to colonel, but subordinate to major-general. While the corresponding rank of brigadier general in many other nations is a general officer rank, the British Army considers it a field officer rank. The rank has a NATO rank code of OF-6, placing it equivalent to the Royal Navy commodore and the Royal Air Force air commodore ranks. It is also equivalent to a brigadier general (1-star general) in the United States of America.
