Yes. It is. It is sad and yet so bizarre.
I have ridden on tanks in the Marine Corps and this is precisely why it is frowned upon not to mention that tanks are big targets and being close to them in certain instances is dangerous. The visibility for the driver is poor and they tend to run over things. The concussion from the muzzle blast when one is close is stunning as well.
Terrible event, especially at a family gathering.
The tractors on the farm my father grew up on had slots at the front of the fender with a protective rubber grommet in them. You could sit on the fenders with a decent hand hold place.
We used to drive 2000 miles up there on summer vacations in the family truckster. I had a place in the back to sleep or play in with no car seats mandatory, back in those groovy ‘70s.
Tanks are nothing but artillery, rocket, RPG, and bullet magnets, I always tried to stay as far away from them as possible.
