If you can qualify in bad weather, how would you handle Soldiers using that as an excuse?

I already know the answer to this. So, I don't really need an answer. Let's put it like this.

I'm currently in Kuwait and have been waiting for far too long to go north. A couple weeks back, we went to a range near Buehring. The weather was very inclement, and camels were all over the place. I went up to group and zero, and I did so with little to no effort. I only needed 12 rounds. Then I went back to throw my lead down range. When the NCOIC gave the order to fire, my first round ended with a click. There was so much sand and dust blowing around that my weapon had clogged up just from chambering the first round. I even had to use all my upper body strength to pull the charging handle back and pry the round out. Throughout the whole 40 rounds, my weapon malfunctioned three times. After that, I just stopped caring, to be honest. In the end, I walked away with 35/40. Out of all the 80 other Soldiers out there, I had the highest score. Queue the rest of my troops (12). Less than half of them qualified. Their excuse, "my weapon wouldn't fire," or "I couldn't see." As bad as this range went, the one good thing I got out of it that I hope everyone else did, keep your weapon clean and maintained at all times. I was very annoyed to hear them all complain about how bogus the range was and the weather. They actually had it much easier than myself, because after my firing iteration, we waited till the wind died down before anyone else went. One said, "the wind curved my bullet, like from Wanted." I later schooled that Soldier on physics at 25 meters, as they were all shooting paper targets at 25 meters. I fear the day any of them go outside the wire one day, with the excuses they come up with.
