The Sniper is usually the fourth unlocked unit of the Progressive Era. The Sniper has moderately low damage and defense, but long attack range and moderately high speed. It gains a defense bonus in bushes and forests, and is effective against light units, e.g. Conscript, but vulnerable to both fast units and heavy units.
It has the skill "Dug-in", giving it a defense bonus if an attacking unit is more than 2 tiles from away.
