The Royal Valkyries

The United Nation and United Kingdom All-female Royal Valkyrja Special Infantry of The Queen's Order, often shortened as "The Royal Valkyrja Marines"; is a specialized unit of the British Royal Marine forces, later expanded to acquiring personels from other countries of the UN, including, but not limited to: Russia, United Kingdom, United States of America, Poland, German, Australia, Japan, Middle-East countries such as Uzbekistan and Afghanistan.

History
It was unknown when did the unit was first founded; with some records stated that the unit was founded at the height of WWII, while some wrote the unit was founded after WWII. The British government have since kept the information classified Tier 0.

2 years prior to Queen Elizabeth II coronation in 1951, the specialized unit was originally a branch of supports, consists of women mechanics and medics, which later expanded to infantry-women.

After the Queen's coronation in 1953, The Royal Marines provide specialized trainings with the SAS 22nd Regiment under the commands of Her Majesty, thus make all Valkyries "SAS Selection Certified".

During the Cold-War, The Royal Valkyria has been known to be the most proficent force of intelligence and defensive, and at the end of The Cold War, 200+ personels have been issued The Victorian Cross.

Later in 2000, The Queen's order to expand the unit to the United Nation was approved, and more than 60000+ applications were submitted. To the current day, there are at least 4000+ personels that are currently serving the Valkryja Force over the world (only 6% are from the United Kingdom due to grueling selection test).

Despite being a unit of the Royal Marines, just like SAS, the unit is not commented on by either the British government or the Ministry of Defence due to the secrecy and sensitivity of its operations.
