There is something very obvious about the picture - some have their hands in front (3, 6-9, 11, 13, 14), one has his hands by his side (5), and some have their hands in back (1,2,4, 10,12,15) (position of parade rest). Plus, why is that one on the far right off by himself? And, there are "groups," 1-5, 6-11, 12-14, then 15.
