TS Vulcan Cannon Upgrade Icons.gif

A Vulcan cannon was an anti-infantry defense upgrade for the GDI component tower, used during the Second Tiberium War and the Firestorm Crisis.


A Vulcan turret mounted a pair of 20mm Vulcan cannons, which were effective against enemy infantry and light vehicles such as attack buggies and attack cycles. However, it should be noted that rocket infantry had better range than a Vulcan cannon and could therefore destroy it from outside of its range.

However, against Tick tanks and heavy assault units like the cyborg commando, it proved ineffective, both because of its limited range and the lack of firepower.



Vulcan cannons were replaced by watchtowers following the Firestorm Crisis.
