So, to kick some more interest in, I wrote up a bunch of vehicle choices. Like the guns, they don't represent any real vehicles, but anyone familiar with the AFVs of the world will recognize the inspirations. No arguing - that's why they have made up names, so that they're not beholden to "real" specifications. The national origins are just for flavor, but can effect things like mechanical reliability and finding parts. I've also assumed that whatever area this takes place in has the usual third-worldy panoply of military surplus and export model junk - the names can be changed to reflect whatever the setting calls for.
Every vehicle has Armor, Speed, and Range ratings. These are all absolute values, not relative to vehicle type. However, they're not linear either.
For Armor, Red represents 'armor' like a car would have - might stop shrapnel or a pistol bullet, but it's not real protection. Each level up represents being able to shrug off another 'level' of gunfire. After around Green, the vehicle is immune to any gun a person could carry, and is only vulnerable to serious anti-armor weapons. This level of protection might include reactive armor, which does nasty things to people around the vehicle when it goes off.
Speed isn't linear either, since it has to stretch from nearly immobile artillery to aircraft when I get to them. Between Red and Light Green represents increments of about 10-15mph, with Red starting around 20mph. Green is equivalent to a car, capable of probably 100mph on a good road. Obviously, driving off-road will slow down anything. The more massive the drivetrain, especially tracks, the less a vehicle is slowed by rough terrain.
Range is how far the vehicle can travel unsupported, namely by fuel. Naturally, most military forces travel with a large supply train in tow. As a rule, AFVs carry enough fuel to travel 300-400 miles with the tanks full. The scale represents ranges up or down from that by 50mi or so.
I'll define the weapons further later, but they should be pretty self-explanatory for now. Definitions- Turrets are enclosed, movable structures that hold weapons internally, protecting the crew. Mounts are open, movable structures, like a gun shield. Pintles are just open hardpoints, they usually hold Heavy Machine Guns, but could hold any heavy weapon in theory.
I haven't bothered designing any strictly civilian or support vehicles or other special stuff - I think everyone can pretty well imagine the capabilities of cars, heavy trucks, and speedboats. If police forces need some paramilitary armor, the Transports can double as SWAT-type party vans. I haven't gotten to aircraft yet. There's a lot of possible helicopter types, and I'm not too familiar with what sort of military aircraft an enterprising revolutionary could get hold of.
