Rover
The Rover is a fast scout vehicle that's cheap to build and perfect for gathering intel on your enemy.
Use a few of them to take out your opponents metal extractors at the start of a game.
It's far from ideal for fighting other non-scout combat units, however, in large numbers a Rover swarm is an effective way to draw enemy fire or even take out unprotected expansions.

Groundhog
The Groundhog is a stealthy minelayer/minesweeper vehicle that can lay mines on the battlefield and detect nearby enemy mines.
Always place mines outside of your opponents line of sight so they're not detected.
It has a mini-radar jammer to hide from enemy radar, and using mines is a cheap way to secure your flanks or expansions without defensive structures. The easiest way to place a minefield is using the Queue Command or Grid Building commands.

Blitz
The Blitz is a fast assault tank with a dual rapid-fire cannons for close combat engagements.
It's light armor and short range makes it susceptible to defensive towers and Pounders.
It is slightly more powerful and faster than the Pawn and Grunt on flat terrain, and is useful for taking out unguarded economy structures.

Shellshocker

Construction Vehicle
The Construction Vehicle can build basic T1 structures and is an effective unit for expansion on relatively flat terrain.
Use multiple on a single structure to increase build power.
It's quite slow going uphill. Escorting it with a few Blitzes when expanding usually is a smart thing. Each constructor also increases the player's energy and metal storage capacity by 50.

Beaver
The Beaver is an amphibious construction vehicle that can travel both on land and underwater.
Use multiple on a single structure to increase build power.
It can can also build additional naval structures like the Construction Hovercraft. Each constructor also increases the player's energy and metal storage capacity by 50.

Whistler
The Whistler is a medium-range missile truck that can out range most Tech 1 defensive units.
Keep them in a line formation since they can't shoot over each other.
It doesn't fare well in close-combat, so always keep it at a distance using the Fight command. Combine it with Janus, Stouts, and repair units for a devastating front line push!

Pincer
The Pincer is a light amphibious tank that can travel on land and underwater.
Use them to invade enemy territory from underwater.
It is weaker than most tanks, but can avoid defensive positions by going underwater and emerging at the enemy's shoreline.

Stout
The Stout is a medium assault tank that has relatively high HP, so keep it infront of your units to tank incoming fire.
Useful for taking down light defenses with its sheer force.
It needs some micro skills to prevent it being D-Gunned, so try to keep enemy Commanders at a distance. Combine it with Whistlers or artillery for a great front line push or raiding enemy bases.

Janus
The Janus is a twin rocket launcher vehicle that has a short-range but does a heavy amount of damage.
Combine with Whistlers and repair units for devastating enemy defenses.
It is quite slow in speed and fire rate, which makes it susceptible to fast moving units like Grunts. However, it also has a large area of effect (AoE) and can destroy almost every Tech 1 bot in a single shot.

Umbra
The Umbra is a mobile radar jamming vehicle that keeps units within its jamming range from appearing on the minimap.
Use it with cloakable units to make them totally invisible and undetectable.
It is best used to mount a surprise attack and to hide your units or structures from long-range weapons. Beware units can still be detected if the enemy has a intrusion countermeasure system.

Prophet
The Prophet is a mobile radar vehicle that gives you intel on enemy units within its range.
Keep it behind your army so it doesn't get taken out.
It doesn’t have any weapons and has rather low health, but having intel on your enemies whereabouts is crucial.

Gremlin
Gremlin is a stealthy tank that, when cloaked becomes impossible to spot for your enemy. Equipped with light plasma weapon and having weak armor it doesn’t stand a chance facing other T2 units. Don’t use it for fighting.
Use packs of 4-6 Gremlins to sneak in beyond enemy defense lines, get intel on plans and sabotage the economy.
If you see an unguarded base try to first disable its buildpower (destroying construction towers) making your opponent unable to react. Then go for Energy Converters to get a nice big chain explosion and finally strike Fusion Reactors and other eco. It can be detected if it comes into vicinity with enemy units or if your opponent has an Intrusion-countermeasure system.

Consul
The Consul is a handy construction unit that can run fairly quickly and provide build-power wherever you need it.
Useful for producing extra units while on the move.
Its purpose is to have a source of mobile build power that you can quickly move to wherever you need it. It's also used to build mines for securing your flanks and areas of high tactical importance.

Mauser
The Mauser is a heavy artillery vehicle that can out range most defensive and mobile units thanks to its great range.
Target grouped units to benefit from the splash damage.
It moves very slowly and will be helpless alone, so be prepared to defend it with units or keep it behind your defensive line.

Jaguar
The Jaguar is a fast light tank equipped with a lightning cannon and a light anti-air turret.
Useful for protecting long range units from fast unit swarms.
It deals a good amount of damage in close quarters combat, but lacks armor to fight against heavier units like Tigers.

Shredder
The Shredder is a mobile anti-air flak gun that deals high damage with a large area of effect (AoE).
Use it to support your army and defend against enemy aircraft.
It can shoot down all T1 and most T2 aircraft, but has limited range and no weapons to fight against land units.

Advanced Construction Vehicle
The Advanced Construction Vehicle can build Tech 2 structures and opens the door to an advanced economy.
Start by building Advanced Metal Extractors and a Fusion Reactor.
It's quite slow, so try to escort it with a few defensive units. Each Tech 2 constructor also increases the player's energy and metal storage capacity by 100.

Turtle
The Turtle is an amphibious tank equipped with pop-up cannon and heavy armor.
Use its amphibious ability to evade enemy defenses through the water.
It has more health than its CORTEX counterpart, the Alligator, but it is also slower.

Ambassador
The Ambassador is a stealthy rocket launcher that fires its missiles straight up to hit enemy units from a high angle.
Use it as the perfect siege weapon to destroy enemy defenses and units from far away.
It can easily target structures and units behind walls or high cliffs, and has unmatched range within T2 mobile units. However, it costs quite a lot to build, and is helpless against fast units.

Bull
The Bull is a general purpose heavy assault tank equipped with a plasma cannon and significant armor.
Build in large numbers to overpower your enemy with sheer force.
It is more expensive than its CORTEX counterpart, the Tiger, but also deals more damage with a larger area of effect (AoE).

Starlight
The Starlight is a mobile tachyon accelerator vehicle that delivers a devastating amount of damage.
Always keep them behind your main units and spread out.
It can take out most units, including Tech 3 units with enough hits, and can out range other defensive structures. However, it is quite costly and doesn't have much armor.

Thor
The Thor is an experimental terminator tank that's equipped with a heavy lightning cannon, dual EMP lasers, and an EMP missile launcher.
Perfect as a front line unit and close quarters combat.
It can stun enemy units while dealing some of the highest DPS in the game, and has plenty of health for tanking incoming fire. However, it is relatively slow and vunerable to bombers.
