Why Btonze Age?

But designed for different purposes and employed for different purposes. Also, and that's the point I'm trying to make, the allies at the start of WWII still fought WWI, whereas the Germans fought WWII right from the start. The secret for their early successes.

The biggest mistake an army can make is to prepare to fight the last war rather than the next war.

I disagree.  Throughout history more armies have lost through failure to learn the lessons of the last war than through failure to anticipate the conditions of the next one.   Admittedly since 1870s the widespread adaptation of the general staff system gave modern armies something of an advantage compare to armies from before that time in terms of systematically digesting lessons of past wars, but there are still many blatant examples of modern armies failing to learn the lessons of the last war.
