and another two tesb's die from bird attacks, one was from a ROK landing on it, the second was from a bald eagle that wanted a replacement hairpiece ripping the tesb's head off,
and regarding the 88mm against 300mm of armour(assuming it is solid metal armour), all you have to do is load H.E.A.T. shells & fire, but it would be easier to destroy with a 120mm as the impact of the 120mm shell would crush them, and if they do upgrade the armour them switch to H.E.A.T. or penetrator shells, then they die just as quickly.
