  • accuracy, n.

    The Guardian, 4 December 2015:

    There is confusion over the way the military uses terminology. “Precision means you can hit the object you wanted to hit and nothing else. Accuracy means that the object is indeed what you thought it was,” Joshi said.

    “You can have a very precise strike on a suspected truck carrying militants, but it would be inaccurate if it turned out to be carrying civilians. Missiles can be precise, but only intelligence and surveillance can bring accuracy. This distinction is being lost.”
