Holy crap, check out this video:
These guys are flying.
I wonder if it helped the horses' courage to be in large groups while galloping at breakneck speeds over giant obstacles? Seems like if one stopped he'd pretty much be rammed from behind. Might instill a "go or die" element to the training?
It's sobering to think these horses were being trained to charge into battle under fire. I can't imagine doing a BN cross country course while dodging bullets. Not cool man, not cool!
