Follow Poot, he's in an M16 that falls in the earth, after about a minute of falling he is removed from film viewer.
But...he is still there in game, the base and town were flashing because of him, and GV dar was visible. Subsequent film attempts by other players showed no enemy vehicle as well.
I quessed where he was with sound and fired an HE round where he actually happened to fall through the earth, no effect.
