Private Server Static Modlist (as suggested by Goodson)
In reference to the Challenger 2, it may be worth waiting for the RKSL one which is currently in development. Also the RKSL Typhoon is also in the works and would be a fine addition to the mod pack.
RKSL StudiosAlso i will have a go at converting that Challenger you posted Howl to A3. I recently converted the F117, F22 and the GLT Missilebox from A2 to A3 (for my own use) with a reasonable amount of success, and as long as the model itself doesn't have too many definitions from A2 then i should be able to work around it.
