The 1,475 life-sized silhouettes, known as Standing with Giants, depicts the number of men, under British command, who were killed on 6 June 1944.
Made from recycled advertising hoardings, then hand-cut into shape, they have been installed across the parade ground at Fort Nelson in Hampshire.
Standing with Giants was created by Dan Barton, from Stanton Harcourt, near Witney in Oxfordshire, who described the work as "The People's Tribute".
It will stay at the fort up until 26 January, because of high interest.
