That was my Dad's job, in the Western Desert in 1941-43; Royal 
Artillery, Battery Survey Party for a 25pdr unit (and later on 5.5 
inch guns). A bunch of blokes with a couple of jeeps and a 15cwt, 
whose job it was to scout and survey the gun positions for the next 
engagement. I still have some of his tables, notebooks and a 
double-cursor slide rule with gunlaying data on the back....
