Rear admiral is a flag officer rank used by English-speaking navies. In most European navies, the equivalent rank is called counter admiral.
Rear admiral is usually immediately senior to commodore and immediately below vice admiral. It is usually equivalent to the rank of major general in armies. In the U.S. Navy and some other navies, there are two rear admiral ranks.
The term originated in the days of naval sailing squadrons and can trace its origins to the British Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies.
