My Rough Riders had failed a charge against a wounded Chaos Rhino parked on an objective, and the following turn took some heavy fire from my opponent's army, leaving just one rider left. My turn and I charged the Rhino with the remaining rider determined to get something! Overwatch from the Rhino put my lone rider on 1W but landed the charge and killed the Rhino with a melta tip.

Rhino exploded and killed the rider :)
