In vietnam it's on the vulcan top left on the map you can go there with special du monde with riding down the hill very fast.
In Russia snow it's at those strange walls (same place in first mission) there sumwere on such a block so you need vertical boost car
And last map is somewhere in the air at the town you need to find the jump to get it.
