Staff Officers in Middle East

[Philip Wilson]

Here is a group photo - the reverse of which is clearly a postcard with the following recorded

'Staff Officers in the Middle East 1914-18 - WY badge on the cap of the Officer on the right - back row. '

Are you able to help me identify who these officers are please?

Has any body seen this photograph before? I found this today in a bundle of original photos in the Warwickshire Yeomanry Museum there being no clues as to who it might have belonged to or how it was acquired. The WY Officer is a Lieutenant. There are several WY Lieutenant's who served on the Staff during the Palestine conflict. This might be Lieut A.D.Hordern who was an ADC but to whom I am uncertain at this stage.
