Captain (Capt) is a junior officer rank of the British Army and Royal Marines and in both services it ranks above lieutenant and below major with a NATO ranking code of OF-2. The rank is equivalent to a lieutenant in the Royal Navy and to a flight lieutenant in the Royal Air Force. The rank of captain in the Royal Navy is considerably more senior (equivalent to the Army/RM rank of colonel) and the two ranks should not be confused.
In the 21st-century British Army, captains are often appointed to be second-in-command (2IC) of a company or equivalent sized unit of up to 120 soldiers.
