Military police joined hundreds of mourners at a small rural church in Derbyshire for the funeral of a colleague killed last month in southern Iraq.
The funeral took place at the church where Corporal Aston was married
Corporal Russell Aston, 30, was one of six members of the Royal Military Police shot dead during protests in Al Majar al-Kabir, near Basra.
The soldiers had been defending a civilian police station which came under attack.
Corporal Aston, leaves his wife Anna, 31, and 17-month-old daughter Paygan.
Hundreds of friends and residents packed St Mary's Church in Coton in the Elms, Derbyshire where Corporal Aston grew up.
The soldier's coffin, draped in the Union Flag and laden with his treasured red cap, white ceremonial belt and regimental bayonet, was carried by six military police colleagues from his unit.
Members of Royal British Legion branches from across the Midlands flanked the church with raised standards and fellow Red Caps formed a guard of honour as the funeral procession marched inside.
Platoon commander Captain James Hibbert told the congregation: "To us Russ was invincible, surely no one like him could simply die.
"He seemed too quick, too strong and too full of life to die.
"He seemed impervious to danger, he was a loyal friend, an outstanding soldier and an exceptionally proud father."
Corporal Aston's father Mike said: "I shall always miss him and I shall never, ever get over his death.
"But I stand here today feeling 10 feet tall with pride because few will ever equal what he achieved."
