There was a wall right there in front of him that would have offered awesome support for the weapon. If he needed covering fire while he moved than why didnt he ask his teammates who were right near him.
Personally, I dont care how he fires it. I just find it funny how people are defending his way of firing it but would critisize an American soldier for doing the same thing.
That's because it was an English Soldier firing it which means to us brits that:
a) He had assessed the nature of the target in front of him
b) He had ensured there were no friendly targets downrange that could be hurt
c) That on balance it was a measured and sensible response to the threat in front of him.
We don’t have the same confidence in American troops, because we think our troops are considerably better than any one elses.
