No offense taken Machz. I could have been more clear it was an observation, and certainly was not suggesting or supporting grave desecration, even during war.
The cemetery in question is at Seoul Union Church, near Yongsei University, on the SW side of Seoul Korea just north of the Han River, and was started about 1880.
At the start of the Korean War June 25, 1950, the North Korean / Chinese armies took the city of Seoul within 3 days after invading. According to the locals, a massive battle on the first day of the war took place at the cemetery and surrounding area.
Many small caliber rounds hit the grave stones, (assumed to have been used as cover by both forces involved based on hits on all sides of the markers). An Army veteran pointed out the differences, and noted where the forces were likely located, including .50 cal machine gun(s).
Many of the stones were decimated and some replaced.
It was pretty clear the differences in projectiles.
