dicking screen
v.— «We’re about to cross a river, and I ask the reason for stopping here and having the men deployed around the place? “The reason for stopping is that a bridge by its nature forms a vulnerable point,” another of the men says. This is where they might have what is known as a “dicking screen.” “It’s very easy for locals and or insurgents, to view military traffic crossing this bridge, therefore we put in place what we call a “dicking screen.”» —“Dangers remain for British in Iraq” by John Humphrys in Basra, Iraq BBC News Oct. 23, 2006.
