I believe the Sargent stands-out amongst the others for his fierce gaze and concerned countenance. His uniform is the only one equipped for late 1930’s early 1940’s warfare, with his uniform buttons covered to further camouflage him in the field and not catch the sunlight for snipers, and his trousers are wrapped for field duty to keep out water and debris. While the others look ready for the parade ground, this Sargent is ready for the foxhole.
He also sits in the foremost position of the delta formation of the troops creating an impression he always leads at the head of his troop.
