Why Btonze Age?

The Germans had cavalry too in WWII. But the horses no longer served as chargers. They only served as means of transportion for the soldiers to dismount when action started. But they were still called cavalry. As far as I know, even the US forces found it hard to let go of the tradition. Weren't or aren't there still units being called cavalry, although there are no longer horses but copters involved?

The last cavalry charge in American history happened in the Japanese invasion of the Phillipines.

Forgive the brevity of this earlier reply, I was on my phone at work. Yes, the US still has the 1st Cavalry Division (Airmobile) in its order of battle. It is currently a combined-arms division. It does feature a horse-cavalry detachment, used for demonstration and morale missions.
