A horse bucks as it jumps over smoke from a grenade during a practice session for members of the Dutch cavalry in Scheveningen, Netherlands, Monday, Sept. 16, 2013.

The horses were exposed to smoke grenades, and harsh sounds to reduce their chances of being startled by any incidents during the ceremony.
