A Group Captain is an RAF rank, equivalent to a naval Captain and an army Colonel.
Generally, an Army unit commanded by a colonel is called a brigade, regiment, or group. See related links for information about different military organizations and units.
In the Army, a Colonel typically commands a regiment or group, which is comprised of two or more batallions. It varies, but might be 3,000 - 5,000 troops. In the air force, Col. would typically command a wing or group, but fewer airmen and officers, maybe a few hundred.
colonel
This is filed under US ARmy and US Navy, so let me clarify.. A Captain in the Army is pay grade O3, whereas a Colonel in the Army is pay grade O6. Colonel is the higher of the two. The Navy has a different rank structure for officers than the other branches. A Captain in the Navy is 06 - equivalent to Colonel. The rank of Colonel does not exist in the Navy.
In most military's, an army colonel is several grades higher than captain. In the United States Army, for example, a captain is an O-3 while a colonel is an O-6. That is switched, so to speak, for most navies. A captain is the highest rank just under admiral. Note, though, that navies don't have a colonel rank.
