Leaving range damage is like not repairing after a car accident or years of neglect. It was not "earned" legitimately. Battle damage is another category altogether. For example, some fellows I know are working on a Saracen armoured car. It suffered from split welds, water ingress and rust damage. But, after priming they found a bullet-like gouge in the plate beside the driver's hatch. This vehicle was used in Northern Ireland, so it is not unimaginable that some unhappy Irishman fired a shot at it.

In the case of the Otter, I like the suggestion replicating the Battle Damage Repair techniques. The inventive use of existing or salvaged parts to make urgent repairs should be the story, not the question of how it was damaged.
