Her commanding officer said in a tribute issued by the Ministry of Defence: “Lance Bombardier (LBdr) Ciara Sullivan, ‘Sully’ to her friends, was to all who had the privilege of serving alongside her, a bright light in any room she entered.
“An immensely professional soldier and an exceptional jockey, she approached every day within The Troop with an infectious energy — the kind that lifted those around her without effort or intention — and was unfailingly present for her comrades in both the small moments and the hard ones.”
