I put at "Reproducibility" "random" but "always" it would have been better.
In most cases the repairing don't work.
All wheeled cars or wheeled armored weren't fixed in any way. But with IFV -Panther with disabled gun was not repaired until I brocked one track, and a M2A1 Slammer with brocken track was not repaired until I brocked the gun too.
This destroy the gameplay, as the big problem with not saving bulbs shot http://feedback.arma3.com/view.php?id=23273
