When letting a horse out to pasture make him turn so he is facing the gate, make him stand until your are in a position where you can safely remove the headcollar and slip out the gate before the horse has time to spin around. Stand fence side of the horse so you don't risk being jumped into. If turning out a few horses (with a handler each) space them out so they arent in kicking distance of each other and release them at the same time to stop the other person being dragged away.
If a horse is being rude, I ask horse to yield his butt away from me, or back up a few steps, so he learns getting the field side of the gate doesn't mean he can dissmiss my authority. He has to yield to my authority and listen to me before he is allowed his freedom. Eventually he should learn the lesson doesn't end until I am walking away from him
