Fuel rod

Fuel rod is a colloquial name for a form of explosive munitions used in several Covenant weapon systems.

Overview
Fuel rods are caseless, transparent projectiles, containing a green, radioactive substance composed of energetic meta-materials and strained-bond lattices -- an imperfect form of Forerunner infusion gel. Once they strike the target, the radioactive materials contained in the projectile detonate. The contents and effects of the fuel rods are similar to the incendiary gel used in Mgalekgolo's assault cannons. Fuel rods are most often used in an anti-armor or anti-air role, but are also devastatingly effective against infantry. They are essentially the Covenant equivalent to the UNSC's M19 surface-to-surface missiles.

At least two UNSC classifications of the Covenant's fuel rods are known.

Class-2
The Class-2 fuel rods are unguided, 38mm in diameter, and are used in the Fuel Rod Gun.

Class-3
The fuel rod cannons mounted on the Anti-air Wraith and the Banshee use the heavier Class-3 fuel rods, which have a greater range and a capability to track heat signatures.

Etymology
Though widely used among UNSC personnel, "fuel rod" is actually an informal term supposedly originating from common popular culture depictions of nuclear fuel rods. Rumors surround fuel rods, with many UNSC Marines under the apparent belief that even carrying a weapon that uses them for ammunition can cause Boren's Syndrome.
