The SAS has been based at Hereford for decades, and now the unit's long association with the city is being celebrated in a new art work.
Royal Academy sculptor John Maine has started creating a stained glass window and stone sculpture to be installed inside Hereford Cathedral.
The artwork, named Ascension, is due to be completed in April 2017.
Col Rupert Pritchard, President of the SAS Regimental Association, says that the work reflects the SAS' philosophy and ethos and its understated excellence:
"This is very much a piece of art, and an abstract piece of art, but put together with a very simple brief that we wanted it to be powerfully simple but have meaning - that it was also to be not boastful at all, but to... reflect our understated excellence".
Ascension will cost £1 million, and is being funded through donations by the SAS Regimental Association.
It's hoped the installation will become a focal place for soldiers, their families and the wider community.
The SAS was founded by Army officer David Stirling in 1941 as a specialised commando unit formed to carry out dangerous missions in North Africa, such as destroying enemy aircraft inside their own airfields.
It was later designated as the 22nd regiment of the British Army for its regular unit, and as the 21 and 23 Special Air Service Regiments for its territorial and reserve units.
The 22 Special Air Service Regiment was based at Hereford following the Second World War and there's been a strong association between 'The Regiment' and the town ever since.
