In the United States Army, brigadier general is a one-star general officer, with the pay grade of O-7. Brigadier General ranks above
Colonel and below
Major General. Brigadier General is equivalent to a rear admiral (lower half) in the other uniformed services.
To be promoted to the permanent grade of brigadier general, officers who are eligible for promotion to this rank are screened by an in-service promotion board comprising other general officers from their branch of service. This promotion board then generates a list of officers it recommends for promotion to general rank. This list is then sent to the service secretary and the joint chiefs for review before it can be sent to the President, through the defense secretary for consideration. The President nominates officers to be promoted from this list with the advice of the Secretary of Defense, the service secretary , and if applicable, the service's chief of staff or commandant. The President may nominate any eligible officer who is not on the recommended list if it serves in the interest of the nation, but this is extremely rare. The Senate must then confirm the nominee by a majority vote before the officer can be promoted. Once a nominee is confirmed he or she will be promoted to that rank once he or she assumes a position of office that requires an officer to hold the rank. For positions of office that are reserved by statute, the President nominates an officer for appointment to fill that position. For all three uniformed services, because the one-star and two-star grades are permanent ranks, the nominee must still be screened by an in-service promotion board before the nominee can be sent to the Senate for approval.
All brigadier generals must retire after five years in grade or 35 years of service, whichever is later,[6] and all general officers must retire the month after their 64th birthday. However, the Secretary of Defense can defer a general officer's retirement until the officer's 66th birthday and the President can defer it until the officer's 68th birthday. General officers typically retire well in advance of the statutory age and service limits, so as not to impede the upward career mobility of their juniors.
