Quite an interesting read about how UAF have dramatically increased the effectiveness of Dutch\German Pz2000 systems.
The source seems very credible , but points out that the modifications are perhaps less secure than the native software.
I will also point out that germany delayed sending MARS 270 MLRS systems ( of which they have 100+ in storage) because it would take them months to update the software.
