Here's something that just crossed my mind. I never served in armour and those I know who did never experienced or knew someone who experienced this.
What is it like for the crewmen inside when 500lbs of HE go off under yer belly? Or when a 125mm sabot rounds makes solid contact?
And second in this same tank, CadSea, that they tested the rounds on. You said the crewmen repaired it then got in and drove off. If these crewmen had been inside would they have been killed or injured? To what extent?
As an aside... I have heard of some documentary-like footage of testing sabot rounds on an old M60 Patton with goats inside. The narrator claims the force of the penetration of the round created an increased atmospheric force inside the sealed turret which crushed the goats bodies and the exit created a vaccum which sucked them out a very small hole virtually liquifyting them in the process.
