Battle map of Roi-Namur

A 4th Marine Tank Battalion M4A2 carrying away a trophy Type 94 tankette after the fighting on Namur in March 1944. The  Marine 4th Tank Battalion was one of the first units to adopt the practice of layering the sides of their tanks with thick timber planks as a counter-measure against Japanese Type 99 magnetic mines.

A P-40 flies down the beach at extreme low level, as Marines practice an amphibious landing somewhere in the Pacific. In order to get this photo, the photographer standing on the beach would have had to have his back to the oncoming P-40 trusting that pilot would do a “buzz job” of the beach and not his hair.
