British, US and German officer ranks
In the British and Commonwealth Armies, a Brigadier is a Colonel in command of a brigade, who wears the insignia and title of such assignment. In the Royal and Commonwealth Navies, a Commodore is a Captain in command of a naval task group, flotilla or squadron, who wears the insignia and title of such assignment, and flies a broad pennant (as opposed to a flag) from his flagship.
In the Royal and Commonwealth Navies, a Midshipman is junior to an Army 2nd Lieutenant and an RAF Pilot Officer. This is because historically Midshipman was a training rank; nowadays however, officers only join as Midshipman if they are under 20 years of age. Because of the duration of training very few midshipmen reach their commissioning board before automatic promotion so the matter of what type of commission they are serving under is of little consequence.
Not listed are US warrant officers. In accordance with Army Regulation (AR) 135-100, Department of the Army Pamphlet (DA Pam) 600-11 and Army Field Manual (FM) 22-100 (para A-3), a warrant officer is an officer who can and does command, carry out military justice actions and sits both selection and promotion boards. A warrant officer is a single-track specialty officer, initially appointed by the Secretary of the Army, he/she receives a commission upon promotion to Chief Warrant Officer Two (CW2).

1 Paygrade is used in the US military as to normalize the equivalent enlisted and officer ranks respectively. For example, the base pay of an E-8 is the same in the Air Force and the Army. In theory, those two E-8s will have equivalent levels of seniority and responsibility. When enlisted men from several services are together, the senior enlisted man is responsible for the group.
