Jake Tutt, 22, claims the ordeal — in which comrades also forced him to drink their urine — left him mentally scarred and effectively ended his military career.
He also alleged he was partially deafened by gunfire and explosions during training after losing his ear defenders, and then told to “stop being a p***y”.
The ex-squaddie is fighting the Ministry of Defence at London’s High Court, claiming at least £200,000 for trauma and hearing loss.
Court documents allege he was bullied and harassed while serving with the Princess of Wales’s Royal Regiment in Paderborn, Germany in 2019.
His barrister Sabrina Hartshorn said: “He was forced to strip, wrapped in toilet paper and sniper tape and set alight, while having to consume food and drink mixed with semen and urine.”
Ms Hartshorn said the ordeal followed a series of other incidents including being forced to jump into bins to locate “random items” while being shot at with a BB gun.
She also claims he was headbutted by a corporal.
Mr Tutt, of Eastleigh, Hants, was medically discharged from the regiment in March 2021.
The MoD was given time to file a defence on a date to be fixed.
