Vionix, Gadgethm, and I have determined that there are far too many nice vehicles to not get a description. So, here they are.
Vehicles of the Colony's civilians and services.
Ford RF-67 "Barricade" Police Cruiser

The Barricade was a special request from the governor of Klendathu, who felt that the standard police car of the colonies had no style. The barricade reflects design qualities intended to intimidate the populace. With style.
Built by Doomcop.
Ford RF-66 "Musaro"

The Civilian Version of the barricade.
Chevrolet "Whippet" Pickup truck

Intended to mimic the "retro" feel of 1950's western car design.
Government Motors L5 "Sierra" Standard Police Enforcer Vehicle.

Holy stuff the governor was right oh my god aaaaaaaaaaaaaa
MBT-8 Riot Engagement Unit

A tank used by the colonial police force, armed with an automatic grenade launcher/HMG. Saw significant action in the insurrections.
Tanks and Military vehicles of the Colonial Army
MBT-5 "Wyvern"

The Wyvern is the standard tank of the Confederation. As such, all colonial defense forces are equipped with this vehicle. It's the backbone of the confederate military, with almost all armored roles being filled by variants of this tank.
SPAAG Type 45 "Flurry"

The flurry is the product of multiple xeno raids involving low-flying aircraft. Since SAM launchers were unable to get an accurate fix, the confederacy developed this variant of the Wyvern. It is remarkably effective not just against aircraft, but also large crowds.
APC Type 3 "Morian"

The Morian was developed from the Wyvern at the same time as the flurry, to update the antiquated and obsolete Type-2 APC.
MBT-5mod2 "Ram"

The ram is the demolition tank/tank destroyer of the confederation, delivering devastating firepower from its powerful mortar. This tank makes a special (and vital) appearance in one of the missions in the campaign.

Ammo Carrier "Mule"

The Mule is essentially an MBT 5, sans turret. It is capable of reloading tanks and infantry anywhere in the field.
SPAAMS "Wespe"

The standard Surface-to-Air Missile system of the confederacy. Ineffective with helicopters and other low-flying aircraft.
APC Type-2M

With the Type-2 becoming obsolete, a medic on Apsolus I Found that they still make excellent Medical Transports. It is now the primary medivac vehicle of the confederate military.

M76 Lorry

The M76 Lorry has three distinct variants:

The flatbed, used primarily as a supply truck.

The Troop transport version.

The bunker version, developed to quickly create and reinforce defensive positions and roadblocks.
