While an essential part of the GDI arsenal, the Juggernaut artillery walker was ill-equipped to repel close quarters assaults from infantry. After one too many Juggernauts were destroyed by little more than a Nod infantry regiment, a frustrated GDI Engineering Corps jury-rigged an infantry-capable garrison pod onto the walker's chassis. The end result was so successful, not to mention devastating to the ill-fated Nod recon patrols that came across it, that this updated walker, nicknamed the Behemoth, was soon approved for full development.
The Behemoth combat trials were carried out by the Steel Talons experimental combat technology division. It was expected the vehicle would see general deployment afterwards.
The Behemoth was succeeded by a newer Juggernaut design, which ended up being the general issue vehicle for the Third Tiberium War. The new Juggernaut did not have the infantry pod, but had the ability to bombard long distance targets.
Aside from the garrison pod, Behemoths look virtually identical to standard Juggernauts, sporting three large assault cannons that can pummel enemies from an impressive distance. However, the Behemoth lacks the Juggernaut's ability to fire on enemies from across the battlefield with a Sniper Team's aid, as snipers were not a part of the Steel Talons' arsenal. Behemoths do splash damage.
The Behemoth can crush most Tier 1 and Tier 2 vehicles as well as heavy infantry by simply walking over them, and can do so without suffering any penalties to movement speed.
