Mustered as Driver at Moascar, Egypt.
Not much is known of his responsibilities here, but this letter from another soldier to his loved ones gives a little bit of an idea what life was like there, just a few months earlier: http://ww1satchell.weebly.com/8-march-1916.html
Here is the service record of another soldier who was also originally ranked as driver, it includes some parts of his diary and some photos: http://empirecall.pbworks.com/w/page/49236549/mackley%20w%20g%20%20%20%20driver%20%20%20%205319
