I wouldn't read too much into a set of glasses getting broken. I had a friend whose glasses were broken when the curtain airbags in his car deployed, and that by its very definition is a low-explosive charge.
But I guess I must have missed the bit about the carbon coating. I would assume that this is something that only covers the areas of the tanks occupied by its crew, otherwise we wouldn't see things like tanks taking battle damage.
As for that high-powered charge? I think that maybe the writers were letting that Japanism about student bodies governing themselves go a bit too far, as I'm sure that in all reality, they would have needed to get clearance from the officiators in order to use it due to the dangers involved.
