Help please You walk down the road between the rice paddies. There are Vietnamese in every paddy, bent over working. None of them looks up when you pass. Then all of a sudden a mortar shell lands right in the middle of the patrol and a couple of guys
you've been buddies with are dead and a couple of others are screaming in agony. The Vietnamese are still working in the fields as though nothing has happened. Did one of them lob the mortar? If so, which one? Should you kill all of them or some of them?

What does this tell us about Vietcong tactics?
