Rear Admiral in the Pakistan Navy is a senior flag officer rank and is abbreviated as R/ADMPN to distinguish it from the same ranks offered in other countries, although there is no official abbreviation available for a Pakistani rear admiral. Rear Admiral may be also called as two-star Admiral to distinguish it from other insignias such as three-star Vice Admiral and four-star Admiral.
Since it's the third-highest rank in the Pakistan armed forces with high classification scale of Grade 21 coupled with additional powers and benefits, the law of Pakistan restricts the use of unsanctioned power by a two-star Admiral and can be constraint under a certain constitutional amendment.
