You airstart above Zolna airbase (L5). The truck is in the middle of TriDuby airbase (L6-1).
Distance is less than 10 km. Head 315°. Slovakia map.

I don't know since when it's indestructible. It worked fine with the 4.13.4m. I never play with the 4.14m and 4.14.1m (DS incompatible with HyperLobby). Bugged with 4.15m too.

I don't try other artillery objects.
This one works fine:
