In what was believed to be the first of its kind in New Zealand, the New Zealand Army and Royal New Zealand Air Force combined to drop an army truck from a Hercules aircraft from a height of about 230 metres (750 feet).

But that was just a teeny-weeny Pinzgauer; I look forward to watching Scout-SV do the same out the back of C-17.
First drop for a Pinzgaur. Plenty of experience with heavy load drops with other types (there’s an especially bent and dented Series 3 lanndrover that got frequently abused for the purpose at one of the air bases).
@ Chris – Might want to upgrade that to a C5 Galaxy
