I just killed two guys who were armed to the teeth and had been playing for a long time. One of them had an AKS74u, and a lot of mags, the other had an M4A3 CCO, which I took, and no ammo.
They had just cleared out some northern town, and I was about 130 meters away in a pine tree. They had a lot of good loot oh lawdy.
PVP is fun.
