The way that all stacked units are presently destroyed en masse if the 
defender loses is simply incorrect. A large number of units should offer 
greater resistance to attack, not be more vulnerable. Real-life armies mass 
troops to increase effectiveness! The present conditions pertaining to cities 
and fortresses (units engaged and destroyed one at a time) could be the 
default situation for all combat except missile attacks.
