Slingers have an attack bonus of +3 against archers and also have 3 pierce armor. They have a small increased attack against walls and towers, but it is only +0.6 so not that relevant for the game. Ships, infantry (assuming the Slingers do not run for it), and cavalry can all take them out very easily. They are easily overpowered by Bronze Age units and are often obsolete by that time.
Team bonuses added, Palmyrans: Technologies which benefit Slingers are researched 30% faster.
Slingers lose their attack bonus against mounted archers.
Slingers move at 1 tiles/s.
With update 93001, Slingers have +3 attack against all archers and 3 pierce armor.
History[]
“
Slingers were light troops who threw stones at the enemy, causing casualties and disrupting formations. A barrage of heavy stones could cause wounds and bone fractures. The stone was held in a cloth sling and swung in a vertical loop to build centrifugal force. One end of the sling was released, launching the stone. Slingers were an alternative to archers and javelin men. They threw stones of different weights, depending on the range to the target. Roman art shows slingers throwing rocks the size of grapefruit, probably at short range. Specially shaped stones could be thrown accurately to a respectable distance. The best known slinger of antiquity was David, who slew the Philistine champion Goliath in single combat with a shot to the head. A contingent of Rhodesian slingers were part of the 10,000-man mercenary force whose march home from Persia is described by Xenophon in his book Anabasis.
However, an Elite Slinger was planned with +10 hit points, +1 range and Line of Sight, +2 pierce armor, +1 pierce attack, +3 vs Archers, but no attack vs Defensive structures.
