WW2 US USN Navy Grey Aviation Machinist’s Mate 2nd Class Rank Insignia

The WW2 US USN Navy Grey Aviation Machinist’s Mate 2nd Class Rank Insignia is a uniform patch worn by enlisted personnel in the United States Navy during the Second World War. This insignia denotes the rank of Aviation Machinist’s Mate Second Class (AMM2c), a technical rating responsible for the maintenance, repair, and servicing of naval aircraft engines and related systems. The patch features a grey background consistent with USN aviation working uniforms of the period. Central to the design is a silver eagle perched above a specialty mark depicting a two-bladed propeller, with two chevrons below indicating the 2nd Class petty officer rank. The grey coloration differentiated aviation ratings from those in other branches, allowing for rapid identification within naval aviation units. These insignias were typically sewn onto the left sleeve of Navy uniforms and remain a recognizable artifact of WWII US naval aviation history.
