My grandfather, Larry, served in WWII. He enlisted and stationed at Camp Polk. He went through places like New Guinea and the Philippines during the war.
When I asked him if he experienced any combat he said; "yes, I experienced some combat. But most of the time I spent in combat was in a tank. Not too much action there."
A typical day in my grandfathers' life at the time was to wake up at the crack of dawn and get ready for a full day of combat, well at least for the ground troops that didn't have a tank to be protected by. Of course for him, driving a tank was easier then being a ground troop. So that made things a little easier. He told me every day the main thing he did, and I quote, "kep my head low. Anything could be expected." At Camp Polk him and some other troops had a idea to set up a trap to alert them if the enemy tried to get into their base camp at night. They would set up grenades filled with half the explosive powder needed for a full blast, and they would bury them around the perimeter of their camp with their pins tied together by trip wire. Once the enemy would set foot in that perimeter and tripped the trip wire it would pull the pins to almost all the grenades. But the grenades didn't go off right away so the jap that snuck in would just think he tripped on a branch or something. Until the grenades would finally go off and alert the camp to catch the intruder. That's if the grenades didn't catch him before they did. "Yep, I would be dozing off to sleep when a critter or a swift breeze would set those damn things off and wake me up again. Then you're stuck setting them all up for the rest of the night."
The thing that stuck out most in my grandfather mind he said was; "looking forward to go home". The war got tough in many ways and situations which made my him wish he was home with his family again.
I asked him if he thought about the war very often now and he said; "so so. Not a lot ....
