This is a definite advantage to the shooter, the vehicle moving directly away from him and the downgrade of the street, and he being in an elevated position made an almost stationary target while he was aiming in, very little movement if any.772

Oswald's Marine Training

* * * when he fired that [212] he had just completed a very intensive preliminary training period. He had the services of an experienced highly trained coach. He had high motivation. He had presumably a good to excellent rifle and good ammunition. We have nothing here to show under what conditions the B course was fired. It might well have been a bad day for firing the rifle--windy, rainy, dark. There is little probability that he had a good, expert coach, and he probably didn't have as high a motivation because he was no longer in recruit training and under the care of the drill instructor. There is some possibility that the rifle he was firing might not have been as good a rifle as the rifle that he was firing in his A course firing, because [he] may well have carried this rifle for quite some time, and it got banged around in normal usage. 781
