They are part of the 65-strong team of wounded, injured and sick (WIS) military personnel and veterans who will represent the UK at the Games.
The eight members joined teammates at the Honourable Artillery Company in London today (Tuesday, 29th October).
Each of the team have their own powerful recovery story and will compete in a variety sports this year.
Over 350 military personnel and veterans trialled nine sports for one of the 65 Team UK places.
The team will compete across athletics, archery, wheelchair basketball, cycling, powerlifting, indoor rowing, wheelchair rugby, swimming and sitting volleyball.
Hannah Lawton, of Help for Heroes and Chef de Mission for Team UK, said:
“The 65 men and women selected to represent Team UK will not only gain a personal recovery benefit from taking part in the Games, but they will hopefully inspire others suffering with life-changing injuries or illnesses that anything is possible.
"Our competitors are proudly serving their country again and showing that they will not let their injury or illness define them.
"As a team, we are especially proud of the fact that 89% of Team UK have never competed in the Invictus Games before.
"The legacy of the Games is strong and they are providing a gateway for more wounded veterans and service personnel to benefit from the Help for Heroes Sports Recovery programme.
"We are very proud to be working alongside these 65 athletes and wish them the best of luck as they embark on their Invictus Games journeys.”
The Games are delivered by Help for Heroes, The Ministry of Defence and The Royal British Legion.
