I have been trying to track down more on this place but Aussie records are short on of this British Training Area.
But the AOWH by Gullett has some details page 533.
But he stated 1918 we started to send cadets there in Dec 1917.
Zeitoun was a large British training Area, courses were going on there for NCO's and officers, these included the skill at arms courses like, Musketry, and MG (Lewis, Hotchkiss and Vickers) courses. They also ran fighting courses like bayonet, trench warfare and bombing courses. Then they also ran the prom courses for NCO and officers like the cavalry and Officer general courses as well as a Topography course for officers. An interesting course for NCO's and officers was the Range Finding/Taking course.
I am sure I missed some of those courses, as finding a list of the units there, and what they did has been a problem, But both officers and NCO (with some soldiers) spent some time at this place leaning the skills of a soldier and officer in the Army.
As to war went on, the appointment of officers was made more formal, this included the introduction of a form (no name or number) or Application in 1916, from the CO, to the Bde commander, then Div commander, see personal file page 24 for this officer;

This also came in another form see page 54 this mans file;

These forms (both types) were only used for a short period during 1916, then they disappear some time in 1917
