Thanks! It looks like the number I posted is about double the actual MBT strength.
I also read that Israel (from the link) lost quite a number of tanks to wire-guided munitions in the past. I'm beginning wonder about the usefulness of tanks with so many different types of tank killers around these days. At least at the start of a major conflict..
