One of Corporal McNeil's three brothers, Jason, has paid tribute to his brother on behalf of his family.
In a statement released by West Mercia Police, he said: "Geoff was born in Ballymoney, Northern Ireland and dedicated his life to the 1st Battalion, Royal Irish Regiment. He served his country with the highest degree of honour and dedication.
“He was a much loved son, brother, uncle and friend and touched the lives of all who had the pleasure of meeting him.
“The family would like to give thanks for the continued support of the army, police and all who knew and loved Geoff. Our love for him remains as strong as ever. Rest in peace soldier. Faugh-a-Ballagh.”
The Ministry of Defence has sent its condolences to the family of a soldier whose body was found at Clive Barracks in Shropshire on Saturday.
A murder inquiry has been launched by West Mercia Police following the death of the 32-year-old, and a 23-year-old man has been arrested.
A spokesman said:
Our thoughts are with the family and friends affected at this difficult time. We are assisting West Mercia Police with their investigation and it would be inappropriate for us to comment any further at this time.
