D'you think the Army charge soldiers for a new tank when the one they're in gets written off ?
You get disciplined if you damage equipment; it's put on a NMD Form (Negligence, Misuse, and Damage Report), and you would lose out financially. You go in front of your boss, no coffee, get quizzed, and if found guilty, you would lose money direct from your pay.
Normally if you crash a vehicle and it's found that you're at fault, you'd be charged the equivalent of an increase in insurance premium.
I've lost a fair whack of money over the years for urinated mattresses, crashed vehicles, lost army identity cards, and knacking a bayonet (I used it as a chisel and then it wouldn't fit on the end of the rifle). If you lose equipment you get billed for it too. If it's over a certain amount you get charged, disciplined, and also billed for it.
