An ex-soldier from Merseyside is suing the Army for more than £300,000 over claims he was the victim of a campaign of bullying and abuse.
Lee Nelson, 23, of Seaforth, alleges he was threatened and assaulted while serving in Iraq and Northern Ireland.
He claims the abuse started after he took compassionate leave following the death of his grandmother.
A Ministry of Defence (MoD) spokesman said it was not appropriate to comment on the legal proceedings.
'Punched and kicked'
Mr Nelson's lawyers have issued a High Court writ, claiming damages against the MoD for allegedly causing or permitting Mr Nelson to be bullied and for failing to provide him with any proper psychiatric assessment or treatment.
The soldier's claims include allegations he was kicked on an injured ankle by a superior and, on another occasion, was held down while another soldier punched him.
Mr Nelson added that one of his commanding officers threatened to kill him if he reported the abuse.
He enlisted in the Army in January 2002 and underwent training in Northern Ireland before he served as a ranger for the Royal Irish Regiment.
It was during his training period that he said he was stigmatised for seeking time off to cope with the death of his grandmother.
Mr Nelson, who left the Army in November 2003, is said to be suffering from post-traumatic stress order as a result of his time as a soldier.
