If you are new to WW2 history understanding rank insignias certainly helps to identify and verify information. Insignia’s were positioned on the upper sleeve on both arms and centered halfway between the shoulder seam and elbow.
We have put together a simple guide to rank insignias with the first in our series being USA non-commissioned insignias.
Please note there were colour variations of the insignia dependent on the type of uniform/season and the ones shown are representative.
