No info beyond that it was an R.O.K. gun. Edited. I did find this story though so I’m including it.
"SEOUL — One researcher was killed and five injured when a field gun exploded Thursday during a test at a South Korean firing range, the defence ministry said.
A spokesman said a 40-year-old official from the state-run Agency for Defence Development (ADD) died and five other researchers were in hospital, two of them in serious condition.
A 31-year-old suffered injuries to both arms and a 36-year-old was badly injured by shrapnel, officials said. Three others were slightly hurt.
The accident happened during the testing of a fuse for shells for a 155mm howitzer. Ministry and agency officials were investigating the exact cause of the blast at Pocheon, 40 kilometres (25 miles) northeast of Seoul.
A spokesman for the Defense Acquisition Program Administration, which oversee ADD, said the explosion happened after the researchers inserted the fuse into a shell for testing.
The fuse was part of a new batch of shells to be produced, the spokesman said, adding the explosion came after the sixth shell to be fired was loaded into the howitzer.
