Jar*Head, it was small because it was a 102 Howitzer. WE had 6 of them which we had to use every night and we moved a lot. There are very few roads in Nam so everything came by chopper. We could lift these guns with a CH47 but for the larger guns we used a flying crane like this.
Everything including ammo, food, water and replacements came by helocopter.

Here is a site where I also was. You can see Fire Support Base Illingsworth from the air.
We were attached and fought for 6 hours here. We lost a lot of us but this was the battle that allowed us to go into Cambodia.
I was the Commo Chief
