A third uniformed ambulance corps volunteer was assaulted by paratroopers on Bloody Sunday, the new inquiry probing the shootings heard today.
Mr Charles McMonagle, a trained first aider with the Knights of Malta, told the tribunal in Derry he was "roughed up" by at least one member of the regiment after treating an injured man in Derry's Bogside on January 30th, 1972.
The Saville Inquiry reinvestigating the killings of 13 Catholic men that day heard last week from another member of the order, Ms Rosemary Doyle, who claimed she was shot in the face with a rubber bullet from close range - her gasmask saving her from greater injury.
Earlier this year, Mr Charles Glenn, who helped Bishop Edward Daly tend to the dying Jack Duddy, recalled being assaulted three times by troops that day.
Mr McMonagle claimed he was confronted by a soldier who had moments earlier been shooting from the hip into the Rossville Flats car park - where one man was killed and others wounded that day.
He was the second witness at the Guildhall in Derry today to describe a soldier shooting from the hip.
Earlier, another man, Mr Danny Deehan, spoke of his "shock and disbelief" on witnessing a similar scene, insisting that troops were facing no threat at the time.
Mr McMonagle said he immediately put his hands up as the paratrooper came towards him and added: "I had my back to the wall. I was terrified and did not know what to do. "I was in genuine fear for my life. He was shouting and screaming at me although I could not tell what he was saying because he was wearing a gasmask and so was I.
"Because I could tell that he could not hear what I was saying, I started to frantically point towards my Red Cross badge. I was shouting, 'Red Cross, Red Cross'.
"The paratrooper then moved up to me and pointed his rifle at my chest and continued to shout at me. Another soldier then came from my right. They both roughed me up. At one stage they took my kit bag and rifled through it."
However, his account was challenged by Mr Edwin Glasgow QC, acting for most of the soldiers, who said Mr McMonagle's written account from 1972 suggested the soldier - possibly the man known as Lance-Corporal V - put the rifle to his chest but left him alone when he realised his paramedic status.
Mr Glasgow asked: "It is terribly easy, in view of everything that has happened to slightly exaggerate the evil of what these soldiers did, is it not?"
He replied: "No, I don't think so."
