More than 50 years have passed since the definitive Battle of Long Tan but its memory was strong in the minds of people who attended an anniversary service in Orange on Sunday.
The Vietnam Veterans' Day Commemorative Service was attended by about 100 people in Robertson Park.
Eighteen Australians were killed in the battle on August 18, 1966.
Two soldiers from the region, Tim Cutcliffe and Henry 'Ted' Suttor, were among more than 500 Australians killed in the Vietnam War.
President of the Vietnam Veterans Assocation of NSW Central West Sub-branch Lindsay Wright said the day was about comradeship.
"It's just to remember what happened," he said.
Mr Wright said he was called up for national service in 1967 and went to Vietnam for 12 months in 1968.
