Sir Addicus Barnabey Harper "Sniper" Greenfield OBE, is a villian in the Zealand series.

Zealand and Greenfield engage in a fist fight atop the Berlingmoore Hotel Complex where Zealand notes his "Tremendous upper body strength" to which Greenfield sarcastically thanks him for the compliment, and sends Zealand flying through the air onto another building. Greenfield pulls out an Sniper rifle and attempts to assassinate Zealand, but Zealand finds a brick and throws it at Greenfield, causing him to lose his balance, and fall forward to his death.
