That reminded me of a time I was in Japan and was able to attend a demonstration by their Ground Self Defense Forces. I really don't remember much I saw that day, the typical tanks and helos, marching formations and whatnot. But one demonstration did stick in my mind. A squad of men on mountain bikes raced down a mountain. As they approached the bottom, they locked their handlebars in place and, maintaining speed, unsheathed rifles and assaulted through an imaginary enemy at the base of the hill.
Wikipedia tells me this may have been the bike they were riding, the Honda XLR250R, although I don't see the rifle sheath. Maybe my memory is faulty; maybe the rifles were slung. Or maybe it was a different bike. Anyway, here's a photo from Wikipedia:
This reminds me of bicycle infantry units. Maybe I'll do a post on that next.
