So where, pray tell, is this documented ?, and how exactly does one "play the odds" to ones favour, is this witchcraft, a hidden skill ?,
Ah, a good question.
Attack with overwhelming force. That is a truism in the real world as well as in Civ.
Face it, history is rife with examples of technologically or numerically inferior forces winning the day through creative tactics. These are the exceptions, of course, just like your tank's loss to an archer was the less likely than the alternative. If you had 100 such tanks attacking 100 such archers, the tanks would win quite a bit more than they lost.
