One of my favourite WW1 Images is this, taken by Ernest Brooks at Gallipoli and showing a British soldier looking at a grave - does anyone know which unit the man was? The caption on the AWM page (I can't find it on the IWM site) doesn't mention - the man has a Long Lee Enfield, and to my eyes his large pack looks to be a 14 pattern one owing to the look of the straps at the back and top looking like the leather ones (hard to explain but the way they dangle, and are rolled on the top, are unlike how the 08 webbing equivalent would look)
