In my prime, I was airborne recon sniper. You can't get much tougher than that. We did it all in those days because we HAD to do it. Nobody asked for slack and none was given. You drove on and on. I learned to do 900 meter silhouette shots and did so with regularity at the closer distances. I went to places where no other American had ever been nor will ever be back to visit. Here's a photo of me, my sniper rifle and a pig I nailed while on a patrol one day. 173D Airborne: The ONLY way to go.
