The Sniper is an unused unit in "OpenRA - Red Alert". It can only be built if debug mode is enabled and "Build Everything" is ticked, or on maps with custom rules that enable it.
Previously, the sniper was a Soviet infantry unit that required a Radar Dome. It is cloaked while not moving or firing. It was removed in Release-20150424.
There are some unkillable Soviet snipers on the cliffs on map Fort Lonestar. It is also buildable in this map.
