Vultures are ideal for scouting and dealing with small-sized ground units such as zerglings, zealots, marines and firebats. Given that vultures are not very durable, they are most effective when using hit-and-run attacks to harass the enemy and are not recommended for large scale attacks. Vultures are also effective hunters against units such as high templars, defilers and other ground-based spellcaster units and can get rid of an expansion base's workers in little time.
