>That these two battles separated by over 2000 years and with completely different weaponry, still share the same basic plot, is to my mind amazing.

I agree. I also found it fascinating when they mentioned how when placing the wall pieces, the soldier unhooking the segment was at risk from enemy sniper fire, and how a mantlet could be used to protect the soldier. Mantlets has been around as long as sieges and were there to shield trench diggers from castle archer fire. It's incredible how many historical parallels can be drawn here.

I think it really underscores the importance of studying history not just in war, but in all things.
