I'll predict that Zeke will throw boulders at horses, killing them. After that he will release gas to turn them into titans (from wind direction). Anticipating that they are inhumanely fast by themselves and will run from it, abandoning their comrades, he will have other teams at the ready to release another batch of gas (in opposing wind direction). Effectively trapping them and waiting for them to turn into titans.
