Has got to be one of the best lines in the war.
I thought it was funny at the time too -
Earlier in the day, before we got into it with the VC company we ran out of water. We stopped along the river which a had nice clear section in the middle and wasn't too deep. Because I was the junior man in the FO team, I was handed everyone's canteens and was selected to walk out into the river and fill them.
I gave Lt. Graves my rifle (an automatic M-14 with a bipod), took off my flak jacket and helmet and waded out into the water.
Now, there are few thing more intimidating than wading out into the open in the middle of water that comes up to your chest in a war zone. You are entirely without cover, easily seen from any direction and if someone shoots, you see the impact of the rounds in the water if you're lucky enough not to be hit immediately. Escaping is nearly impossible because nobody, no matter how strong, can run quickly out of the water.
I edged out to the middle and cautiously started filling the canteens, one by one - then a rapid and very loud burst of fire cut through the water just yards in front of me. I threw the canteens and struggled and thrashed to get out of the water and make it to shore as fast as I could.
When I got to the shore, everyone was laughing and Lt. Graves said "Geez, Rick - you sure have a light trigger!"
