Extended Thermal Lance
Extended Thermal Lance is an upgrade for the Colossus which increases its attack range by 3, from 6 to 9, allowing the Colossus to outrange all static defenses and every ground unit except the Siege Tank.
The upgrade is seen to be essential when getting Colossi, as it enables them to fire from a much safer distance, where there is a reduced risk of their being surrounded and destroyed. Combined with the Colossus's ability to move, and to see over cliffs, this upgrade also allows for greater harassment against mineral lines and buildings, or units outranged by the Colossus.
