Free Basic Units
Soldier
This is where you start, grunt. The bottom of the food chain. The common infantry, dying what you’re good at. You’ve got your basic machine gun and a pistol. You’ll do better to hunt enemy infantry rather than vehicles.
Shotgunner
Range for power is a tough trade-off to make, but if you decide to take your shotgun out into the world, you’ll need to get in close to be deadly, but in close quarters, you’ll mow’em down
Flamethrower
GDI may have the range, but Flamethrowers bring the heat. Perfect for melting lightly armoured vehicles and Harvesters. Perfect for stopping enemy infantry dead in their tracks.
Marksmen
Equipped with a semi-automatic rifle with a 10 round capacity magazine and an inventory of a maximum of 60 rounds. They are most effective against other infantry units at medium range.
Engineer
It’s a thankless job, but somebody’s gotta do it. Weapons? You’re lucky to get a pistol! But, on the other hand, you are lugging around some remote C4, your timed C4 and your repair gun. You can repair infantry, vehicles and buildings, plus that repair gun also disarms C4 and those pesky nuke beacons.
Advanced Units
Officer
Who needs accuracy when your spitting out rounds in a rapid-fire hurry? Not all that effective against vehicles, but you can certainly shred through enemy soldiers.
Rocket Soldier
Got tank problems, huh? Here’s where to start. Start pounding rockets into those Light Tanks and watch them explode before your very eyes.
Chemical Trooper
As the only infantry who can go out into the Tiberium fields without so much as a scratch, use them as your safe spot while you rip through the GDI harvester with your Chem Sprayer.
Black Hand Sniper
Like pulling up the rear, huh? Well, the Sniper Rifle will let you do just that . find a nice dark corner, hide out and pick off enemy infantry at your leisure.
Stealth Black Hand
Now you see me, now you don’t. The Stealth Soldier has the advantage of being cloaked most of the time (you de-cloak to fire, and you are somewhat visible at close ranges, or when hit), so use it to your advantage. Sneak up behind tanks or snipers and give them a little C4 love, or let your Laser Rifle rip into them. Careful, though, the AGT (Advanced Guard Tower) isn’t fooled by your Stealth Suit.
Laser Chaingunner
Got Mammoth Tank problems? Here’s a good place to start. The Laser Chain Gun has a long range and rips through that GDI tank armour at a high pace.
Sakura
For those times where the Sniper Rifle just isn’t enough, try the Ramjet Rifle. Designed to penetrate through infantry armor, the Ramjet Rifle truly is a sniper’s best friend.
Raveshaw
The Railgun has a long range and pinpoint precision. It doesn’t pound quite as hard as GDI’s Personal Ion Cannon, but you also don’t have to take as long to reload either.
Mendoza
The Volt Auto Rifle doesn’t have the range of the Personal Ion Cannon, nor is it as great at annihilating infantry as the Ramjet Rifle, but when you need to stop Flame Tanks, there’s nothing better.
Technician
Being an engineer is a thankless enough job, so why would you want to be an advanced engineer? How about the ability to take down a building by yourself? Chuck both of your timed C4’s onto an MCT, add a remote C4 or two, and voilà . building destruction, party of one! You also sport the proximity mines, although remember your team can only have a total of 30 proximity mines and remote C4s in play at any one time. Any more than that and they’ll start disappearing.
