Saif Sareea 215 September 2001 - 26 October 2001[2][3] Exercise Saif Sareea (Arabic: سيف سريع Swift Sword) is a series of military exercises undertaken by the United Kingdom and Oman which first began in 1986 and most recently took place in 2018.

The exercise was the largest deployment to the Middle East in a single operation by the UK since the Suez Crisis in 1956.

This exercise illustrated a number of problems in the British Army; the traditional "make-do" attitude to shortages of modern equipment and essential spares fell down in the face of the Omani weather.

"[13] The House of Commons Committee of Public Accounts concluded that the exercise had been of benefit to the subsequent British invasion of Iraq, Operation TELIC.

It was the UK's largest deployment to Oman since the previous Saif Sareea exercise 17 years before.

[18] The exercise was the first to be facilitated by the newly-established UK Joint Logistics Support Base in Al Duqm Port & Drydock, Oman.
