Although it is possible to use ground vehicle classnames, the AI is so useless at driving that we gave up trying to make it work reliably.
The CAS and Transport modules are designed to be used with aircraft. Put the following in the init line of the synced vehicle. It is possible to place crewed vehicles in the editor and sync them directly to the CS module, allowing editors to sync additional editor modules to them such as medical modules.
The AI can be really finicky about taxing so make sure you give it plenty of room to manoeuvre. Fast air will require a runway to operate and the related CS Element module must be placed on or near a suitable taxiway. CS automatically detects the side of units placed and will only make it available for use by players friendly to that side. They will request permission to move before setting up, firing their mission and then immediately returning to base to await further tasking. Self Propelled Artillery and Mobile Mortar Teams have the ability to move into range if you request a distant fire mission. Since AI will not reoccupy seats when kicked out by players, pilot seats are locked to prevent accidents. The item required can be changed in the main CS module. By default, players must have a Laser Designator to submit CS requests. Units will spawn at the sub module location.
