After today's partially successful combat search and rescue mission in Iran, we thought it would be interesting to learn where these tactics were developed -- the Vietnam war.

The Sikorsky HH-53 "Super Jolly Green Giant" is a version of the Sikorsky CH-53 Sea Stallion helicopter for long-range combat search and rescue (CSAR) helicopters. It was developed to replace the HH-3 "Jolly Green Giant". The HH-53s were later upgraded as MH-53 Pave Low series. The United States Air Force's MH-53J/M fleet was retired in September 2008.
