In a statement just released, the MOD says he died during an operation in the early hours of 15 October, when the BRF deployed from Camp Bastion into the Nahr-e Saraj District of Helmand Province.
They were deployed to counter an imminent threat to both the Afghan population and the International Security Assistance Force (ISAF). Towards the end of the operation Lance Corporal Brynin’s section became the target of enemy fire.
Together with a sniper and machine gunner of the BRF, Lance Corporal Brynin returned fire, but while extracting from the area he received a fatal gunshot wound.
