Plus if you look closely at that footage of the 1000 lb bomb hitting that tank, you will note there were another two tanks and an APC in very close proximty, which are most likely now not in anything like a good working order
The MBT targetted (and other vehicles) appear to be parked up in some sort of compound, evidently not actually engaged in any action as such. A case of testing out this new combo on a relatively straightforward target with little risk of collateral damage?
