Infantry
Minigunner
- Cost: 100
The basic GDI infantry unit, cheap and quick to train but weak by themselves. They are best used en masse to overwhelm other enemy troops. They are most effective against similar enemy infantry and light vehicles, but should not go up against heavy vehicles without some strong backup, nor should they take on enemy infantry such as flame troopers.
Grenadier
- Cost: 160
Slower and slightly more expensive to produce than the minigunner, but they pack more of a punch. Unlike the minigunner, grenadiers should not swarm the enemy in close bunches, as their grenades can do devastating damage to themselves and their GDI allies. Space them out when defending against infantry and use them carefully against enemy vehicles. They can also launch up hills and over walls.
Bazooka Infantry
- Cost: 300
A very powerful infantry unit, but they move slowly and aren't cheap. Excellent for use against enemy vehicles and buildings when they are in large numbers, but their slow movement means they can get crushed by tanks if they don't get out of the way. They can fire against air targets, but are not too effective against infantry.
Engineer
- Cost: 500
Almost completely defenceless, but an important unit in the game. Used to capture enemy buildings, just make sure they have a good escort to protect them on their way, or place them inside armoured personnel carriers.
Commando
- Cost: 1000
Able to take out any enemy infantry with a single shot and from a good distance. They also carry C4 to destroy buildings, but they can take damage very quickly. Completely ineffectual against enemy vehicles, so they shouldn't go anywhere near them. You can't produce your own commandos, instead you are given one by GDI for the occasional mission.
This unit can only be built in multiplayer games.
Vehicles
Humm Vee
- Cost: 400
- Speed: Fast
- Armor: Light
- Weapon: Machine Guns
A lightly armoured but very fast vehicle. Best used for scouting out the surrounding area, it's not too good in battle by itself and shouldn't take on other enemy vehicles especially the Light Tank.
Additional Notes
As a low tech unit, M998 High Mobility Multipurpose Wheeled Vehicles, commonly called Humvees, traced their lineage to before Tiberium was discovered on earth, and entered the First Tiberium War with little change to their basic design. Basically, Humvees were fully enclosed units with reinforced windows and a powerful engine, and they were armed with a roof mounted 7.62 mm M-60 machine guns.
Humvees were used in the first Tiberium War by the GDI, and featured an M-60 Machine gun for use against infantry targets. The M-60 was highly ineffective against armored targets, although against structures it could could be massed. A large group of Humvees would slowly wear down a structure's armor. Although not as fast as the Nod Buggy, Humvees made up for it with heavier armor, while still being reasonably fast and were able to take out large numbers of buggies. The heavier armor made for a more expensive unit overall. Unfortunately, the armor was not heavy enough to sustain tank bombardment. Generally, Humvees were used as light recon units and anti-infantry support, although they could also be used as escorts for APCs if necessary. As an extremely low-tech unit, humvees were deployed with most GDI task forces during the First Tiberium War. GDI commanders used them against most Nod light infantry in skirmishes.
Nod's Obelisk of Light, as a powerful one hit strike, was sufficient to destroy a Humvee in a single shot. Rocket Bikes were also suited for attacking them, being fast enough to catch a Humvee, and having anti-armor rockets, but their lack of armor meant that the M60 machine gun was often a more than effective counter to this approach. Light tanks could certainly do the job, but were too slow to catch Humvees and destroy them. Flame tanks, owing to their combination of relatively low speed and short range weaponry, were generally not used against Humvees, and in any case would be highly ineffective.
The Humvees were phased out and latter on replaced with Wolverine walkers for recon and anti-infantry roles. And new Pitbull ATVs fullfilling the Humvees' non-combat roles, though not used on the front lines. A number of these vehicles continued to be used even as far as 2047, but were mostly a curiosity rather than a fully fledged utility vehicle.
APC
- Armour Medium
- Weapon Machine Gun
- Cost 700
- Speed Medium
The M113 APC carries 5 infantry but also can shoot machine guns. IF the vehicle is destroyed while carrying infantry the infantry will bail out. Use APCs to protect the Infnatry from danger or for ambushing like load APC with Bazooka Troopers and when a light tank destroys it the Bazooka Men will Surprise it.
Medium Tank
- Cost 800
- weapon single 120 SABOT cannon
- Armour Better than the Light Tanks armour
- Speed Medium
The M1A1 Abrams Tank is more powerful than the Nod Light tank but slower.
Rocket Launcher
The M270 Missile launcher artillery is good against infantry and Aircraft. Not good for Obelisk Guard Towers.
Mammoth Tank
- Weapons 2 missile launchers and 2 cannons
- Armour Heavy
- Cost 1500
- Speed Slow
The X-66 Mammoth Tank is a foe you dont want to mess with. It is slow but heavier armed with better cannons. Use it to protect weaker units like when enemy flame tanks are incoming pull the weak units back and send in the Mammoth. This unit requires a repair bay and the Weapons Factory.
Orca
- Armour Light
- Weapons Just Missiles
- Speed Fast
- Cost 1200
The Orca Assault aircraft fires missiles at its enemies but hates enemy SAM Sites.
