I guess it shows the different ways those at the front found ways to help them blend in and survive rather than have a rifle silhouette itself against a stark white background when things were not on line from the Q store or developed I also used the "Naval type" as a broad reference to the style as they are only using one colour tape not 3 colour's like most naval vessels had as in #3's example as can be seen on the stern and bow ends of the "Laffey" (DD-459) a Benson-class destroyer.
