Yesterday I experienced this bug/glitch on the map Crossing.
I was running along the small river and out of nowhere got killed by the rockets of the Apache Chopper coming out of the stone wall to my right.

Yea, I was gonna get around to making a post detailing how many of the supports just appear out of the terrain (cliff faces or high mountains) on some maps. The bombing drones and the Apache or Minigun chopper the most noticeable of these.

i think the rocket barrage also still has problems, rockets still bounce of surface when water/trees nearby!
Surprise
