Mekong Delta

In 1968 US has carried an Operation Speedy Express in the heavily populated Mekong river delta. The orders were to achieve the high body count at all costs.

That was achieved: 10899 enemy casualties were reported, with only 267 American losses.

The problem? Only 748 weapons recovered. Much of the rest were civilians.
