This FAQ is to address somewhat more detailed gameplay questions and topics.
All units will receive resupply of fuel and ammo when in 'Supplied Territory'. The Supply Level is shown as a strength bar in some of the Land Department panels, and a Supply Level Overlay can be toggled on the map using the hotkey 'S'. Units receive supply when in their own territory, and when in the territory of a region that has provided a 'Transit and Supply' treaty appropriate for that type of unit (Land/Sea/Air).
Units outside of Supplied Territory can also be resupplied by a transfer from a 'Supply Unit' (Supply Truck, Transport Plane or Helicopter). Naval Units (surface and sub) can be resupplied by a Transport boat or by a Transport Helicopter, but not by fixed-wing Transport Planes.
Some air units are also 'Air Refueling capable', which means that they can receive more fuel (but not ammo) from Air units that have an 'Air Tanker' specialty.
Units that use fuel run on either Petroleum or Uranium. To figure out a unit's fuel efficiency, look at its Technical Readout and divide the amount of Fuel the unit carries by its Movement Range. That gives you the units of fuel it uses per Kilometer. Since each Hex in the game represents 16km, multiply your result by 16. Thus:
Movement Range / Fuel * 16 = Fuel per Hex
Military Goods are used to resupply units. To get an idea of a unit's supply efficiency, divide the unit's Supplies by its Combat Time to determine the number of supplies used per hour while in combat.
Unmounted - Often called "Foot" instead of "Unmounted" in the forums. Unmounted troops are literally walking, hence the reason why their speed is so low. These type of units tend to gain a large defensive bonus in close quarters combat. In addition, Unmounted units do not use Fuel to move (which is why it is listed as "0" in their Technical Readout).
Towed - Towed units are assumed to move by being towed behind some anonymous vehicle. The speed for all Towed units in the game is set to 25 kph. All Towed units also appear to be Soft targets. The main benefits of Towed units are their quick build time and their low cost to build and maintain. In the case of Artillery there is also good fuel efficiency to consider.
Towed Artillery has excellent fuel efficiency, while early Towed projectile AA has poor fuel efficiency. This changes however with Towed missile AA.
Wheeled - Wheeled units tend to be faster on Roads and smooth terrain than Tracked units. Often they are also more fuel efficient, but not always.
Tracked - On rough terrain Tracked units are King. A Tracked unit that has a listed speed of 60 kph can go faster than a Wheeled unit with a listed speed of 100 kph on difficult terrain.
This is a new feature in the Global Crisis Expansion Pack. Players are able to trade units and missiles with other human players and to offer them to AI players.
Some basic rules apply:
