Aliases - inkoalawetrust/Military-Vehicles-Pack GitHub Wiki
Most vehicles include alias actors, which can be spawned with the console to spawn different variants of the vehicles. These are useful due to not being able to set user variables through the console, such as for being able to spawn the APC with a certain turret, without needing to open the map in the editor, place down the APC, and give it the User_Turret variable. For spawning vehicles through ACS or changing their user variables, it's suggested to just use SetUserVariable and GetUserVariable.
Aliases for different vehicles can be found on their dedicated pages.
