Interesting Story From The Bush War

From Scattered Shots, an "Interview with Jim Bolen Green Beret, SOG 1-0 and Rhodesian War Vet". An excerpt:

My secondary MOS was light and heavy weapons so I think I have fired just about everything. I have killed the enemy with 9mm, 45, 7.62 and 223 rounds and believe me the 223 is by far the best. It took me a few months in country to get my CAR 15 instead of using my M 16. As far a getting though the jungle and being able to maneuver again the CAR 15 is the best. It is light weight and you can easily carry 400 rounds of ammo.

Also, in the jungle environment where combat was up close and intense, Bolen preferred using tracer ammunition over standard ball rounds. 

I remember my first 3 kills. My point man was crossing a small NVA trail and I went next, there was a slight bend in the trail, as soon as I stepped on the trail 3 NVA regulars rounded the bend, they were walking abreast to each other. We saw each other at the same time. While they were bringing up their weapons I fired from the hip on full auto. I could see just like a laser where the rounds were going. I put at least 3rounds in each man. Believe it or not I could see smoke coming out of the holes in their uniforms where the bullets went in, I will never forget that.
