A British army officer has died following an incident during live fire training in Northumberland, the Ministry of Defence has confirmed. Captain Philip Gilbert Muldowney, 25, died on Sunday at Otterburn Training Area, one of the UK's largest army training ranges.
Captain Muldowney served as a fire support commander in the 4th Regiment Royal Artillery. He joined the army on 5 January 2020 and was commissioned into the Royal Artillery in December that year after attending the Royal Military Academy Sandhurst.
An army spokesperson said: “The circumstances surrounding Capt Muldowney’s death are being investigated, and it would be inappropriate to comment any further at this time.” The MoD described him as an “immensely enthusiastic officer who embraced life with a vigour that inspired those around him”.
Captain Muldowney had served in multiple roles, including a deployment to Estonia in November 2021. He was seriously injured while undertaking a commando course at Lympstone, East Devon, in January 2025, but later completed the fire support team commanders’ course after rehabilitation.
Commanding officer Lt Col Henry Waller said: “It is with deep sadness that we announce the death of Capt Philip Gilbert Muldowney. Always full of ideas and never without a bright smile, Gilbert approached every challenge wholeheartedly.” He described Muldowney as a “rising star” who “consistently put his soldiers first”.
Tributes from colleagues highlighted his authenticity and joy. Capt Helen Brackenbury said: “It has been the pleasure of my career to have served alongside him, and I consider myself very lucky to have been his friend.”
