Charge!

Here's a picture of modern day French Garde Republique charging. Pretty interesting.

After studying the picture a little, I notice that one of the riders (on the left, farthest from the camera) is standing up in the saddle- whether this is an attempt at two-point seat or simply standing up, is a little hard to tell but I suspect it's the latter. Looking at the legs and the lean in the upper body, it appears that the rider is top-heavy and out of balance. If the horse shies or abruptly stops, that rider is going to get launched.

The rider in the center appears to have a better seat and it appears to be a two-point stance with the rider centered low and the calves bearing a lot of the rider's weight. This is far more better than the first rider.

Yeah, I know everyone's a critic. :-)
