Runcorn soldier Ian Sartorius-Jones took his own life
A soldier from Cheshire took his own life while the balance of his mind was disturbed, an inquest heard.
Signaller Ian Sartorius-Jones, 21, died of a gunshot wound in Helmand Province in southern Afghanistan in January.
Warrington Coroner's Court heard he had been having problems in his home and work life in the months leading up to his death.
The inquest heard he was upset he had not been promoted at the start of a tour of Afghanistan last year.
He was also worried he would be fined over a piece of missing equipment.
His father Robert Sartorius-Jones said: "Ian was a loving husband, father son and brother. He will be sadly missed by us all.
"He died while serving his country that he loved and was patriotic to the core. A true hero to us all and will be never forgotten."
The father-of-one enlisted with the the Royal Corps of Signals in February 2007.
He joined his squadron in May 2008 and has since been deployed to Iraq and Afghanistan.
