This first one looks to have been taken in the Phillipines late in the war. This was my maternal grandfather. Looks like he is with the heavy mortars. He'd been demoted to Pfc and transferred to the mortar platoon as a punishment. He was demoted like that at least twice during the war. He made it as high as Master Sgt. but whenever he was in charge of folks, he tended to turn everyone loose to go get drunk whenever possible. Hence demotions and assignment to heavy weapons. Lugging heavy mortars around in the heat wasn't considered a fun job.
He also spent a stint as security element to the flamethrowers as they burned the Japanese out of caves. I think he volunteered for that to get away from the mortars and because he hated Japanese. His job was to stand ready with a Thompson and shoot anyone that came running out on fire. When I was a box he still talked about that, having enjoyed it. Did I mention that he really hated the Japanese?
Note the small pipe (probably of local make) at a jaunty angle and the captured Japanese flag.
I think is was on New Georgia or at the end of mopping up on Guadalcanal. Note the beard, that everyone is skinny, and the ragged uniforms. My grandfather had a similar beard in a photo that was on the cover of Yank magazine that was from the fighting in New Georgia, so I suspect this is from the same campaign.
All dressed up to go on liberty apparently? Note the Errol Flynn mustache.
WW1 Doughboy helmets... This apparently was taken in Hawaii shortly after Pearl Harbor. The fear was quite real of a Japanese invasion so newly arriving infantry formations assumed defensive positions. The leg bag probably held a gas mask?
I'm thinking that this has to be Hawaii again since he never served in the Phillipines prior to the liberation. Note the height difference between the soldiers and the locals and the then exotic coconut.
This last one was taken in Michigan after the end of hostilities and the return home. My mother dates it to Aug 1945, but contemporary newspapers showed my grandfather still in the PI as late as Jan of 1946. Thus I suspect that this is the Spring of 1946 if it was taken in MI. Note the Navy uniform that hadn't changed much until fairly recently on the relative that served in the Navy. If this was taken in August of '45, then it would have been in the PI.
