Australian 9th Division troops under fire from enemy mortar attack atop Ruin Ridge, Alamein sector, Egypt. These troops shelter in a standard slit trench dug waist deep and reinforced with sand bags, rocks and anything capable of forming a barrier between shrapnel and flesh. Tin hats are the order of the day while in typical Australian fashion shirts are not. The Sergeant (with the shirt) is holding a pair of binoculars searching for any sign of where the mortars are being fired at them from.
