Both died at Camp Bastion hospital
Two soldiers killed in separate incidents on Monday in southern Afghanistan have been named by the Ministry of Defence.
Sapper Daryn Roy, 28, of 21 Engineer Regiment, died from injuries caused when the vehicle he was travelling in was hit by a roadside bomb in Helmand.
L/Cpl Barry Buxton, 27, from the same regiment, died after his vehicle rolled into a canal, also in Helmand province.
The two deaths take the total number of troops killed in Afghanistan to 284.
Sapper Roy, from Consett, in County Durham, had been travelling in convoy and intended to provide protection for some civilian vehicles when a roadside bomb went off.
He was taken to hospital in Camp Bastion but died from his injuries.
Speaking to the MoD website, Lt Col Bobby Walton-Knight, commanding officer of 21 Engineer Regiment, said Sapper Roy had been on the brink of promotion.
"He joined the army later than most and brought with him a sense of maturity and common sense that few could match.
"He had quickly proved himself in the regiment, his pursuit of the high standards made him stand out and he was about to move on as a junior non-commissioned officer.
"He never complained, never moaned; he worked hard, looked after his mates and made a difference."
L/Cpl Buxton, of Meir, in Stoke-on-Trent, died after a road running alongside the Nahr-e Bughra canal collapsed causing his vehicle to roll into the water.
His comrades managed to free him from the submerged vehicle but he was pronounced dead shortly after arriving at Camp Bastion hospital.
Lt Col Walton-Knight said he had been "a great soldier and a fine man".
"Friendly and outgoing with a keen sense of humour, he had only been in the regiment a short time but had quickly made his mark.
"He was an inspirational junior non-commissioned officer, respected by his men and trusted by his commanders.
"He had a bright future ahead of him: confident and capable, he would have gone a long way."
He leaves behind his wife, Emma.
