A shredder hub with turrets
Detects stealth units
The Shredder turret is Nod's basic counter-infantry turret in Tiberium Wars.
Firing a volley of high-powered anti-infantry shrapnel from its barrels, GDI InOps commented that the Shredder turret acted like a large shotgun. The shrapnel is powerful enough to penetrate any body armour, making it a good choice to protect the base from all sorts of enemy infantry, even well-armored ones like Zone Troopers.
Just like Nod's laser turrets, as long as the hub remains intact, destroyed turrets will be automatically rebuild, should they be destroyed. However, damaged turrets need to be repaired manually, by repairing the hub.
In the Kane's Wrath expansion pack, the Black Hand and Marked of Kane sub-factions can upgrade their shredder turrets with Particle Beams or Supercharged Particle Beams, greatly increasing their firepower to the point where one Shredder Turret hub can do as much or more damage than even two unupgraded ones, and additionally makes them much more noticeably powerful against heavily armored infantry. Particle Beams also makes them do some effective, though not good, damage to light vehicles and allows turrets to take out Scrin energy fields very quickly. Supercharged Particle Beams has no real difference in effect to Particle Beams on the turrets, except they simply fire faster. The second upgrade available to all Nod factions is the addition of a fourth turret placed on the hub itself.
It should be noted that Particle Beams don't actually improve the base damage of Shredder turrets, they actually drastically improve their accuracy and fire rate. In actual application however, since normal Shredder Turrets have a shotgun-like effect this basically gives the turrets a large firepower boost, as well as reducing the difference in their effectiveness between being used at shorter and longer ranges.
(Marked of Kane only) Supercharged Particle Beams replaces the Shredder's ammunition for particle beams, increasing damage to a point where they can effectively harm light vehicles. These are more damaging than the Black Hand's version.
